AACS "cracked"
Apparently we have us a new DVD Jon at Doom9.org. muslix86 made a program to decrypt AACS protected movies. AACS is the protection used by HD-DVD.
When a HD-DVD is played it's protection key is stored in the system memory unprotected, by grabbing the key you can use BackupHDDVD to decrypt a movie and place it on the hard drive.
The catch, however, is that the program does NOT grab these keys, you will have to add your own keys. To get your key collection started, the program does come with keys for five movies.

Multi terra is close at hand. Plus once ripped a nice compression with little loss, via my GPU.....
whereas blu-ray has about 25gb. They use a smaller laser wavelength compare to the DVDs and CDs, which is the key factor that allows more space on a blu-ray disc.
I am pretty sure about this information, i studied it a while ago
12 cm, single sided 15 GB 30 GB
12 cm, double sided 30 GB 60 GB
8 cm, single sided 4.7 GB 9.4 GB
8 cm, double sided 9.4 GB 18.8 GB
Study harder.
Just in fun Yin. My first comment was to the fact that a higher definition movie will take more space that a standard DVD will, depending on DVD compression type and quality. I just watched LOTR one and two and I see why they put the extras on another disc, better movie quality at length.
A little more about the compression, the extra compression of HD DVD won't make much of a difference right now, if done in something other than MPEG-2(which is horribly outdated, I might add, but some continue to use it). Both formats offer enough storage that the current TV display technology will reach it's limit before the encoding does. This holds especially true if the studios stick to the more modern formats, such as VC-1 (which is basically H.264) 30 GB on a dual layer HD DVD is more than enough for 1080p. Only the most trained eye(those that encode a lot of video) will notice a difference between Blu-Ray and HD DVD. And like I said, you'll most likely only see a difference in the darkest of scenes.
