I added up the releases in the last 90 days and it seems there has been 35 25gig and 39 50gig releases. so its right around 50/50. the previous statement that 25gig is far more preferred by devlopers seems no longer accurate. the outlook on new releases looks about the same. Does anyone disagree? If you want to add in all the 25gig releases since blu-ray came out sure you come up with more. I think 90 days is a fair amount of time to go by and Its possible that since the first releases were in november for 50 gigs alot of the projects in the works were still based on the 25gig discs slowing the ramp up a bit. any thoughts? 71.107.48.182 05:30, 7 April 2007 (UTC)
1) What is PIP? 2) What is the significance of Region codes? Kdammers 02:44, 12 April 2007 (UTC)
--PIP is 'picture in picture'. It used to be a popular thing in the 90's but I haven't seen a whole lot of it lately. On the television it was basically a small box in one corner of the screen that would show another channel or input source. I'm not really sure why it would be important for a DVD player to have PIP, but I'm sure they'll think of something interesting to do with it.
Region codes are significant because a player will generally only play discs from its own region. Manufacturers tend to state that this is to protect end users from device damage due to differences in display rates or voltages, but personally I think it's just a form of market control. So you get some info and my opinion as well... *BONUS!* :) —Preceding unsigned comment added by 71.197.243.144 (talk) 06:28, 15 January 2008 (UTC)
Hi all. We are discussing a new Compare table. Please come in and leave your opinion on the new tables here. --StarChild74 13:38, 17 April 2007 (UTC)
"Nonetheless, if a scratch does occur, there is no current way of removing the scratch without causing further irreparable damage. Abrasion cleaners used in video game stores to clean DVD game discs and movies (by removing plastic and thus the scratch) will not work. This is because the data layer is so close to the surface that even if the abrasion cleaner was able to remove the scratch, it would also remove the data layer destroying the disc."
Does someone have a link of a reliable test that confirms this? Until then I see this as speculation. Ray Andrew say that it is fact. So I guess that you have some proof to show that then, as you know that it's fact? The last part is even written as speculations; '"...close to the surface that even if the abrasion cleaner was able to remove the scratch...". My personal believes is that this is right information, bocouse it sounds right, but should this wiki base on persons believes and speculation? If this is right, then it should be a test somewhere. Until then I will continue deleting this part. And when someone comes up with some reliable proof I gladly put it back myself. --StarChild74 08:01, 18 April 2007 (UTC)
I think I would go with removing the wording. only because I don't think 99% of the population has a home DVD repair kit in thier home. Most I bet just buy a new dvd. If I added up the number of dvd's and cd's I had that are now coasters due to scratches (which I had to re-buy) I would be pretty pissed. the whole "virtually indestructable" line when we switched from cassettes was a riot.. lets not do anything to make that format look any better then it really is..lol You scratch a cd or dvd its just as useless if you don't have a repair kit and if you do have one (at an extra expense I might add) then it "may" work after repairing it but it prob wont a second time.. At least blu-ray added a hardcoating.. and one that seems fairly robust and stands up to quite a bit of abuse.. I give them that much (the hardcoating IS thier abrasion cleaner by preventing as much as possible before they happen. some scratches on dvd's are just too deep to be fixed as well.). I mean if you take the pizza cutter and steel wool to it then find out that doesnt break it so you decide to run over the disc with your car. sure you may need to buy a new one ;). seriously though.. if you don't take care of it.. it breaks.. seems pretty self explanatory to me. has anyone done a test on how different an HD DVD is to blu-ray in the scratch catagory? maybe we should add a note on that article that unlike blu-ray which has a protective coating and is not susceptiple to damage even from steel wool and pizza cutters, a slight scratch on your disk may render it useless causing you to need go out and purchase a home abrasian cleaner which may or may not work... thats just as bad I think. -71.107.48.182 18:40, 18 April 2007 (UTC)
You all are a tough crowd :). It looks like a quick Google search solves everything. From this information it looks like there two options, if its a light scratch (ie does not go through the 0.05mm hard coat) then buffing may be able to remove it without totally removing the hard coat. But if its bigger, then the whole hard coat must be removed (which they admit is dangerous as the data layer is so close), but then the disk has no protection and could easily be damaged. So a rewording is in order, but the topic is still relevant. I'm sorry if I offended anyone earlier, that was not my intent. --Ray andrew 19:42, 18 April 2007 (UTC)
ok... a few things. source one states they have not been able to repair to many because its very hard to find damaged discs in circulation (thats good for blu-ray)and that they were impressed at how difficult it was to actually damage the disc.. even when personally trying to. (I breathe on my dvd and its scratched) source 2 states that the coating gives them a "much better" scratch protection then dvd's (and I imagine hd dvd's as they are made the same). also according to the sources the scratches within the hardcoating come out with what amounts to a "good cleaning" with a buffing machine..the buffing process does not penetrate the hard coating they say...alot better then having to take sandpaper to the disc and prob less risky for light scratches. the hard coating only needs to be removed IF the scratch pentrates the hardcoating completly not even if it does not penetrate as the new verbage states. at that point...the disc will only THEN be as scratchable as easy as dvd's are. I think adding anything about the scratchability is unfair at this point until more data is avail. otherwise it appears we are just looking for a negative. and in fairness if we add something about the scratchability something really needs to be put on hd-dvd and dvd as to how blu-rays coating gives much better scratch protection compared to hd dvds - dvd's in everday use. otherwise we would be playing favorites. thats just my opinion.. maybe I read the article wrong. and remember these are companies who make a profit off fixing discs..not very good for them to be saying blu-ray is very scratch resistant. my guess is if they could they would be saying these things are very scratchy buy our product now to save your discs..... -71.107.48.182 01:18, 19 April 2007 (UTC)
Let's see if I can summarize this.
I think I've got the differences fairly covered. If so, and I'd appreciate a check or two by other editors, something like this info should be in the CD article, the DVD article, the Blu-ray and HD-DVD articles. The differences are relevant to WP as the Average Reader for whom we are writing/editing are not being educated about them, though understanding (and the differences) are important to protecting their data (eg, songs, movies, images, programs, ...). ww 11:08, 19 April 2007 (UTC)
There's a rumor Wal-Mart has requested 20M high-def disc players--some reports say HD-DVD players, but it's not clear; they may be Blu-Ray. I don't think there's anything verifiable enough to be added to an article yet. Discussed at more length at Talk:HD_DVD#Wal-mart_HD-DVD_rumor. 67.180.140.96 05:33, 22 April 2007 (UTC)
The WalMarts in the Salt Lake area have began to sell blu-ray movies.
But no HD DVD titles yet. I speculate whether this is policy or a reflection of sales reality.
Anyone have a source? 71.219.94.15 00:26, 30 July 2007 (UTC)
Tracer9999 undid my revision, saying "previous edit was fine. new edit adds less info".
That was precisely my intention, avoiding unnecessary duplication of content. Moving most of the AACS-specific parts to the relevant article. Then I expanded upon the parts that are Blu-ray specific.
What parts of the old revision (if any) do you think should be added to my version?

I believe this article has too much focus on commercial video discs rather than the physical medium itself. By reading the article it does not become clear which of the DRM restrictions apply to normal recorded data CDs and if its possible not to include DRM. ("The Blu-ray format employs several layers of DRM.")

Virgin Megastore Tower Records at Piccadilly Circus has 4 shelves of bluray and ONE of HDDVD. Bluray is winning. --81.105.251.160 13:25, 1 June 2007 (UTC)
This so called format war is quite irrelevant. Because of the heavily crippled nature of both medias and files contained on them, an user is required to rip both discs in order to safely backup and watch the video recordings without restrictions. The resulting ripped files can be stored anywhere and only their quality matters, and not on what physical disc they were released by the commercial publisher. 83.99.184.75 03:19, 7 June 2007 (UTC) (Not loggen in: J7n)
In the section DRM, AnyDVD HD: "..but they will release no details for obvious reasons". Call me a fool, but I don't know what the obvious reasons are, nor do I want to sit and think it over for a while. --ScarletSpiderDavE 03:37, 8 June 2007 (UTC)
What is the purpose of the AnyDVD HD section? It looks like an advertisement for an unrelated product. Jonabbey 13:24, 3 September 2007 (UTC)
I think it's time for the Blu-ray Disc#Paper based Blu-ray Disc section to go. The reference is three years old. I can't find any evidence that it's been commercialized. The motivation seems sort of weak: it's supposed to be environmentally friendly somehow, yet one could argue that a half-paper half-plastic disc would be difficult to recycle. I tried to find a diagram showing the structure, but failed. Does anyone object to dropping this section? Spiel496 04:22, 12 June 2007 (UTC)
Maybe these points are over-thinking the issue. This disc looks like a PR stunt that was floated for whatever reason, and then dropped. Spiel496 04:12, 19 June 2007 (UTC)
I would like to propose that "Other optical data storage technologies" and "Alternative disc technologies" be merged together. They are near identical, with only one discrepancy (protein-coated disc) that can go in either. 212.32.73.18 19:58, 28 June 2007 (UTC)
The "Other optical data storage technologies" heading is not referenced by any other page (as a wikipedia search confirms), so it can be safely removed while its contents is merged with "Alternative disc technologies" under "See also". The HD DVD page sets a precedent for this, as it has "alternative discs" laid out this way, and it seems to make more sense. 212.32.107.185 16:46, 4 July 2007 (UTC)
Shouldn't double sided GB amounts be added? There on the DVD and HD DVD pages so shouldn't the be here?
Why it is not mentioned that most (if not all) titles sold today on Blu-ray are in fact 720p and not true HD? 81.96.125.17 18:49, 21 July 2007 (UTC)
Uhhh. Because it's not true? I have yet to see a Blu-Ray in my collection or in a store that wasn't 1080p. Googling reveals there apparently are some 720p Blu-Ray movies, but that seems to be uncommon. Perhaps these are the only movies you happened to buy? 24.23.231.54 20:22, 25 July 2007 (UTC)
i haven't seen a single 720P blu-ray in europe, they are all 1080P Markthemac 04:39, 30 August 2007 (UTC)
Despite the list's title being simply "Released Titles," it clearly states that it is listing Blu-Ray launch titles from June 20, 2006. However, the very short list includes Disney's Pirates of the Caribbean: Curse of the Black Pearl, a May 22, 2007 release. This is wrong and very misleading. For instance, it would lead some to believe that the movie is encoded with the inferior MPEG2 format like other launch titles. Others in the list may also need to be verified (only that one stood out to me). Update: Yep. I noticed another: "The Dukes of Hazzard" is not released on BD *at all* according to this list: http://forum.blu-ray.com/showthread.php?t=3112
I think the list likely needs to be scrapped. 72.15.73.29 21:42, 26 July 2007 (UTC)
Or just give an external link to an official listing. —Preceding unsigned comment added by 71.197.243.144 (talk) 06:31, 15 January 2008 (UTC)
The Target announcement was rewritten in such a way that it seemed almost like it was trying to obscure and downplay that Target had decided to sell only Blu-ray stand alone players. I added text based on the article from Forbes to clarify the announcement. 24.23.231.54 05:40, 28 July 2007 (UTC)
Sorry, but what I wrote is quite accurate. Target will carry and promote stand alone Blu-Ray players in their stores. Meanwhile, they are not carrying stand alone HD DVD players in their stores. The article keeps being altered to try to obscure or spin these facts. I guess HD DVD supporters really want this to not be true. This is supposed to be NPOV, and I'm trying to edit the article to include all of the facts beneficial to both sides, but the parts which are good for Blu-ray keep being editted out. Please stop trying to spin it. 24.23.231.54 04:51, 30 July 2007 (UTC)
I'm not here to argue about Blu-ray vs HD DVD. All I have to day about that is that the Blu-ray system seems to have some nice technical advntages, and that not using "DVD" in the name is likely to be an advantage. (There are people who will confuse HD DVD with standard DVD).
But what are the interesting technical features. The BD-J system sounds useful for allowing more interactive content. Depending on exactly what is supported, It could have some cool implications.
I hope that people don't feel that the system is useable only for HD content. SD content on the discs has some very nice properties. A single blueray disc can fit a full season of many SD television shows. It would certainly be nice to not need to include 5 or so discs in the box. Unfortunately it looks like many companies are not going to be willing to make discs where the main content is SD. They may make discs where the extra content is SD, which allows far more extra content to be included. (Although today, I find the problem is that studios have a lot of trouble figuring out what extra content to include, besides a commentary audio track. They simply often don't have anything worthwhile to include. Being able to include 9 hours of SD bonus content is not going to be useful).
Annother cool feature is the 2 overlay frames in HDMV mode. One is intended to be frame specific, and used for things like subtitles. The other can be used to overlay things like buttons. So it is possible to pop up a choice or menu without neededing a dedicated menu screen. The BD-J mode has more flexibilty here.
Also, what features of the DISCs will not get used? For example I suspect that very few discs will use the PIP feature of Blu-ray, which requires a whole second decoding chip. I know that the Multiple-angle feature of DVDs was almost never used. Similarly the seamless branching feature of DVDs was not used often.
