Just chiming in...Blu-Ray has another layer of protection that has not been cracked yet. Could this mean that the major studios may jump ship to blu-ray?

Early doom for HD-DVD? just a speculation

Thats what i get out of this as well. Its so early in the formats lifespan so its not really a problem of ditching the format.

Just a quick point, HD-DVD has generally used the VC1 codec as opposed to BRay's use of older MPEG2 (and hence poor relative quality of their early releases on single layer 25gb discs though both formats can and have used VC1 on their titles).  VC1 is already very compressed enabling a lot of info within a smaller container (the argument behind HD-DVD not needing 50GB discs for films - the codec and compression are supperior to make it a non-issue).

Anyway, the idea of taking VC1 and getting it compressed down hugely without quality loss is a no-go unless there is a whole new generation of codecs.  MPEG2, yes but VC1 no.  The only things to get the size down significantly will be cutting features and/or decreasing resolution.

It's java.. so you shouldn't have to really do.. anything. Though.. you'll still need a proper UDF 2.5 driver that supports reading the HD DVD file structure.

Reducing the movie resolution from 1080p to 720p saves more than 55% of space - so an 18Gb feature off a HD-DVD disc would only take an 8Gb dual-layer disc with no need for quality loss ;-)

I don't know about you but I consider a loss of 55% of the pixels to be quality loss (one more step like that and we are nearly back at SD quality).  This is like playing a game in 1600x1200 and opting for 1024x768 and saying there's no quality loss.  If quality is defined as any resolution meeting HD spec criteria, then yes, 720p is also HD.  But to assume there is no loss of information in dropping over 1/2 the pixels in each frame - that's a tough one to swallow.  720p is certainly good quality, but calling it no quality loss is a major stretch.

Very True of course, but many of us watch our movies on our 720p TVs and not our computer monitors smile.gif

Ewwwww Linux.  Who wastes their time on Unix's bastard child?

Anyhow, this is going to be such a pain in the butt to rip a HD DVD movie to DIVX!  *leaves computer alone for the day*

well I tryed to edit my first post and it did not work so here is how it should have been...

Clap hands and cheer everyone as this is a hoax
you need not waste any more time on this little jar file.

it takes 6 or 7 keys to open and play a HD DVD

to copy to a hd dvd from a disc to hard drive...

this little jar file only uses 2 keys+(title key + encypted footage key)
your HD DVD player is a key+
copying it from a the disc is a wrong usage key+
the replicators media key not even used+
media BLOCK key is an inbuilt block key made from the replicators media key 'not even used'+
PowerDVD is a key not even used as it needs to be in effect to produce a key at all times.

(3 correct keys + 1 wrong key + 3 missing keys = 3 out of 7 keys) = no film footage.....

....as all the keys are checked in a big check sum so that if even if 1 is wrong or missing then
no film can be watched/played/copied/moved....


to play from a hd dvd from a hard drive...(only works if you got the first 7 keys)

title key +
encypted footage key+
media BLOCK key is an inbuilt block key made from the replicators media key+
the replicators media key+
playing the film from a hard drive (not playing the film from a the disc ) is the wrong key+
not using your HD DVD player is a missing key+
PowerDVD is a key used as it needs to be in effect to produce a key at all times.

(5 correct keys + 1 missing keys + 1 wrong key = 5 out of 7 keys) = no film footage.....

....as all the keys are checked in a big check sum so that if even if 1 is wrong or missing then
no film can be watched/played/copied/moved....

sorry and I hope this helps you all to learn about hd dvd aacs.

last years hoax (dec 2005) was to play backed'up 360 games using a xbm disc.

regards.

That's a far too simplistic way of looking at it. If such protection schemes actually succeeded in stopping piracy I might see the point in implementing them but they never do.These protection schemes end up doing nothing to stop the ultimate goal, eliminating piracy, and only end up hurting the consumer. I won't go into the numerous, well documented examples of how DRM affects the consumer but like I stated earlier, google is your friend. smile.gif


I'm sorry...how does DRM hurt consumers?  Seeing as how all copy-protected media I own works as it should, I don't see how it hurts me one bit.  Where as pirating ultimately means that people who pay for legitimate copies of media pay for the pirating.  Hmm?

still think its not a HOAX then

try to play a hd dvd disc like muslix64 did by clicking on the file
'FEATURE_1.EVO'

all you get is a blank/black screen with no film footage and some
audio clicks/buzzes as not all of the keys are present as I described I my
earlier post

to play a hd dvd disc you need to go to the 'ADV_OBJ' folder
then click on one of the 'VPLST000.XPL' files as this has the first key needed
to play the footage and is also the order in which the hd dvd disc plays.

Regards.

After much frustration of wanting to kill someone, I got the first key but trying to create a dump of powerdvd is ridiculous.  I tried googling it and can't find anything.  I tried the ctrl + scrl lock (2x) reg trick but no luck.  If anyone can PLEASE point me in the right direction.  Thanks
