AACS "cracked"

[Deleted member 3]

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.

Obviously you would only be wanting to do this when you backup your HD-DVDs I'm sure

 

[EastCoasthandle]

Yea, that's it...back-up existing HD-DVDs...that what people will do!

muahahahahaa

 

[WarEagleAU]

Kind of crazy, unless you can afford an HDDVD burner and the discs to go with it. Or you want to download HD-DVD stuff and play it on your TV without the hassle. Either way, a bit redundant and stupid if you ask me.

youll be eating them words in 1-2 years

Cap'n we need more drive space!!!!

'terra' drive space

The same was said about DVDs, now you get them for 25 cents and even your grandparents know how to copy them. CDs idem actually, 700MB while your hard drive was about the same size.

Praise the hacking comunity!

you know HD-dvds arent as big as blu ray

 

[XooM]

most are dual-layer for movies, which is a nice 30gb of space per movie. nothing to wag a finger at.

So the reason that storage capacity was increased for HD was................... ahh yes.








Multi terra is close at hand. Plus once ripped a nice compression with little loss, via my GPU.....

Pretty much what I was thinking. A re-encode with H.264s HD profiles should bring those files down to size. Then play them via 360 or something on the HD set.

HD-DVD have provide better quality.... like as in High Definition, I am pretty sure about this, not a ton more space, I think its about 8. something gb.

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

Physical size Single layer capacity Dual layer capacity
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.

blu ray is 25gb single and 50gb dual the new duals have been released and look much better then the singles cause they use a higher bitrate mpeg2 and mpeg4 codecs

HD-DVD are actually lower-quality than blu-ray. HD-DVD only does up to 1080i whereas blu-ray does up to 1080p (iirc)

 

[Wile E]

Both are capable of 1080p, it's just that HD DVD will have to be compressed a little more than Blu-Ray. You'll notice it the most in dark scenes, in what appears to be a slight aliasing effect. Both are still better looking than an up-converted DVD player, your typical HD computer download, or the cable companies' on demand HD content.

.... things change over time, relax people make mistakes

 

[XeoNoX]

im not surprised, i was expecting this. If blue ray doesnt get cracked, then we all know toshiba will be the winner in the blueray vs hddvd battle. people are gonna want what they can "backup".

A bit of orange on the walls too eh?





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.

Exactly.

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.
