Talk:DVD/Archive 2

message: Taw (and perhaps others as well) has repeatedly edited the DVD article to say that the content scrambling system was intended only to enforce region control restrictions, while others seem to think the encryption was intended to try to prevent (or at least reduce) copying.  Perhaps others have the same understanding as Taw.  I suggest that we figure out which view is really the one that is most correct or at least most prevalent in objective reports.  So which is the correct interpretation? (We probably need to cite some sources.) Mulligatawny 04:37, 12 December 2005 (UTC)

message: Some anonymous user keeps reverting the page to include a link to . I contend that the link does not belong because it talks about Blu-ray, which is its own separate format, but more importantly, because the link is entirely in Japanese.  --Cyde Weys talkcontribs 03:06, 13 December 2005 (UTC)

message: "Unlike DVD-Video's CSS, as of 2005, CPPM has not yet been cracked." Has been "cracked" last year. 
source: http://forum.doom9.org/showthread.php?t=96860&highlight=cppm
cracked in the sense that: "I just uploaded to RareWares a tool that enables WinDVD owners to rip full quality DVD-Audio tracks encrypted with CPPM. It does so by launching/patching WinDVD 5/6/7 and redirecting the stream to disk instead of the sound card after decryption.". 131.155.54.18 15:07, 17 February 2006 (UTC)
replies: text: This does not mean that CPPM has been cracked in the sense of the cryptographic elements being compromised as they were for CSS. This is circumvention -- it doesn't actually rip the encoded streams off the disc, it captures the decoded PCM streams. So the point is valid that it's possible to rip audio from CPPM-protected DVD-Audio discs, but it's not correct to say that CPPM has been cracked. --JimTheFrog 07:50, 13 March 2006 (UTC)

message: It has come to my attention (As short as it is.) that the Dual Layer Recording page is not only a stub, but a short and uninformative one at that. If we were to move it to the main DVD page, I'm sure that somebody with more experience in the field than I could rewrite it to be much more informative. Just a suggestion.

replies: text: I would agree.  I'd do it once enough consensus was reached. Idiosyncrat 20:30, 10 March 2006 (UTC)
replies: text: I would also have to agree. I atttempted to find the Dual Layer information by seaching for DVD's and had to find this seperate page. When I read it, I was disappointed to find it not very informative. Brett 22:52, 2 May 2006 (UTC)

text: "More than a few viewers have worried that their dual layer discs were damaged or defective." - Sorry if this is posted in the wrong place, but isn't the wording of this ("more than a few") against Wiki policy? Jpf51286 15:48, 21 August 2006 (UTC)
