Cinavia DRM disabled workaround

**tical** · 07-30-2011,01:13 PM

I have traced the Cinavia DRM checks to 4 separate sprx files and after a long time trying to patch these files I have found that 3 of those files are present in the DEBUG (DEX) firmware don't have the Cinavia DRM checks enabled. Files are videoplayer_util sprx, videoplayer_plugin sprx and videoeditor_plugin sprx.

I have successfully copied these 3 sprx files from DEBUG (DEX) FW 341 over to my retail PS3 unit running OFW 341 using dev_blind and Cinavia seems to be now disabled. I've confirmed this by playing back a number of Cinavia affected video files.

This means that Cinavia is now disabled for all DLNA playback and copying, but Cinavia checks on AVCHD and BD playback are still present with Message Code 3 that mutes the audio as the sprx file with the Cinavia check bdp_plugin sprx is not present in DEX firmware because BD playback is disabled in DEBUG. If someone is able to patch Cinavia out of bdp_plugin sprx this will be solved too.

I have created a new task for PS3MFW so this can be easily made part of any new MFW's as needed. Any FW version that has had the DEX firmware leaked should be able to be used to create a CFW of the same version. eg DEX 3.41 -> MFW 341 or DEX 355 -> MFW 355 etc etc. Don't use sprx files from different FW versions! See git hacks for change_cinavia_files task source.

Big thanks to the KaKaRoTo and REBUG team for their community contributions as this would have never been possible without the knowledge they've shared with us.

thx for your work on this. this crap has bugged my from day one. i have always been worried that IF a cfw comes out that puts us on 3.66 then more cinevia would be in there and i wouldn't be able to play some of my movies. looks like your on the right track and i can only hope that other devs will follow and this will be a built in feature in the cfw's to come. thx again.

as OP has said the files are from DEX debug, so it is a built in feature in REBUG CFW

Edit: good going tical I knew cinevia disabled in REBUG had something to do with the the debug files used

Place the PS3MFW folder on the root drive.

Code:

C:/ps3-mfw/etc/etc

i'm tryeng to unpack the 3.55 rebug PUP to get the sprx files, but i only got a folder with all the pkg's files in.
all i need to do know is to unpack the pkgs to get the sprx.

how do i do that in windows?
thx

I think you can use ES35's Tookit v2 to unpack them.

File name: ES35's_PS3_ToolKit_v2.0.rar File size: 2.57 MB

I have determined that the Blu-ray playback Cinavia checks are actually in the file bdp_BDMV_self (I suspect DVD Cinavia checks are probably in bdp_BDVD_self).

Is there any way to use a firmware file from an older firmware in 355MFW? FW 3.01 didn't have Cinavia at all (the last one I believe), but that firmware can't be used with new blu-ray discs (store bought) because the AACS keys have expired, requiring a FW upgrade... If we could get bdp_BDMV_self to work (and hopefully the AACS keys are stored elsewhere, like in AacsModule_spu_isoself?), that might be a possible solution to bypass Cinavia for Blu-ray (and I assume AVCHD). (I tried just arbitrarily throwing the 3.01 bpd_BDMV into a 3.55MFW, but the PS3 locked up at disc playback... Not sure if that's a file encryption problem, or just that the firmwares themselves have been changed significantly...)

Or would there be a way to create a completely separate application from the 3.01 firmware bdplayer? Something you launch manually from the XMB that would play the BD disc... Not a perfect solution, but better than nothing. If you are concerned about Cinavia, then you are playing from an unencrypted disc, so the AACS keys wouldn't matter...

This is mostly just thinking out loud... I'm totally new to the PS3 hacking world and figured I could beg for some input.
