Concerns of Experts

The quote from Peter Gutmann's paper refers to Windows Vista -- not to AACS -- and some of its claims have been discredited. I recommend removing it from the article as it doesn't really address any concerns about AACS. As of now, I have corrected the factual error and provided a reference to the counter-points, but I think it should be removed. Peter Torr (MSFT) 05:52, 2 November 2007 (UTC)[reply]

I agree with that removal. I also think the print-screen thing is given too much prominence. It should be reduced to the footnote of trivia that it is (like I did the main AACS article. Then again, trivia sections are discouraged).

On the other hand, I'd really love it if this article had a neat table of when the various MKB versions were released, and when they were circumvented. Would require some research, though, and I'm not sure if the sources for all that could be found. — Ksero^{t c} 09:46, 2 November 2007 (UTC)[reply]

Print Screen

"...it was discovered in July 2006 that a perfect copy of any still frame from a film could be captured from certain Blu-ray and HD DVD software players made simply by utilizing the Print Screen function of the Windows operating system. [...] This exploit has been closed in subsequent software versions."

I remember hearing this, but what I heard was the software simply disabled the Print Screen key, while one could still write their own screen capture program and use it just fine. Anyone know if this is true? (Great example of precisely the problem with DRM if it is, BTW.)

And then of course one can run Windows in a fullscreen VM in another OS, and capture that OS' screen instead. :-p 199.126.1.82 01:55, 10 November 2007 (UTC)[reply]

analog hole.

As such, the output data will not be in the form of the compressed video from the disc, but rather decompressed video. This is an example of the analog hole.

This is not really an example of the analog hole. The data is digital and there is no quality loss.--91.47.124.134 (talk) 15:32, 30 December 2009 (UTC)[reply]
