Hacking WindowsMedia9 DRM....

Hi All,
I have bought the new Coral Reef HDTV WMV9 DVD and now want to convert pieces of it to another format to play with it.

Is there any new hack for the WMV9 DRM out yet ?

One way to do it, is to install something like a realtime
capture, that can capture the realtime output from Windows Mediaplayer 9 and capture this to a new file on the harddisk.
Something like http://www.fraps.com/ can be used,
but as far as I have tried, they do not yet support HDTV resolutions,
but it might be, that they just released a new version,... I have to check this out again..
The next step would be to try to hack the WIndows Mediaplayer and
make some external calls to the graphedit programm which allows a hookup externally and then there could be some directshow filters be used to
store the output to a new AVI file with NO encryption.
Has this yet been tried ?
I guess running a few tools in the background, when WIndows Mediaplayer 9 is running, must not be too complicated to see,
how WMP9 dumps the bitmaps to the screen.
Maybe this can just be hacked, so the bitmaps are just written
into a new file, maybe also just in raw RGB or YUV format and could
be later reencoded to a standard XVID encoded AVI file or something like this...
So the best way to hack this bloody DRM is to hack the Windows Mediplayer 9 and dump the output to a file.

Any comments ?

Regards, Stefan.

i think efforts should be focused on a splitter that supports and/or circumvents dmr, so the data doesn't have to be reencoded

Yes, that is right, but if I want to reencode it to an XVID
AVI then I already need to reencode it anyway.

So why does nobody just hack the Windows Mediaplayer 9 to output
raw BMPs to a file instead output to the screen ?

Regards, Harti.

I didn't want to start a new thread since a thread like this already exists.

QUESTION:

"Are there any tools for decrypting DRM (Digital Rights Management) encrypted WMV's?"

OK, I understand encryption and I understand that cracking the encryption is not easy however:

IF:

+ You are entitled to watch the movie.
+ You have the proper username/password.
+ You are able to play the movie.

Can't somebody make a tool that uses that username/password to decrypt the DRM WMV (Windows Media Video) into a regular WMV file?

I did some googling on this and it seems ipod DRM and MP3 DRM has been successfully hacked but can't find anything on DRM for WMV. I thought I would come to DOOM9.ORG because you guys always seem to be on top of things but surprisingly I don't see any info on it here either.

Sure would be nice to get this DRM crap off my PC and burn it to a DVD for later enjoyment.

Pretty much found my own answer which was found in this thread:

http://forum.doom9.org/showthread.php?s=&threadid=76172

It pretty much says that DRM for WM7 was hacked with a program called Freeme but WM8 and WM9 have not been hacked to this date.

It also says that M$ fixed this by "Triggering an update of the security component when a client makes a request to a license server"

I guess it would be kind of hard to allow WMP to access the Internet in order to connect to the license server but, not accept the update!

I guess the best course of action is to not purchase (rent) M$ DRM videos in the first place!

exactly...

i think general concensus is to not even try to break WMV DRM, because that would simply encourage it's proliferation (something i don't think anyone but MS wants in the end...).

MS have done enough to the IT industry, we don't want to let them loose in the entertainment industry too... god knows there's enough bastards in that particular industry.

HDTV isn't MS. it's mpeg-2

besides that, the WMV-HD crap isn't exactly HD, either. it is a vapourware pseudo-standard that will probably disappear as soon as HD-DVD comes out.
