[PC] DeSTRoi - PVR Content Decrypting (only for C/D series)

[shadowrunner256]

Hi,

first, thanks for all the work you guys are doing here!

I've tested some things, and want to give a little feedback...
I own a UE32D5700, PVR enabled via service menu, samygo app, DVB-S.

Copying all the files of a recording session with the same name to a folder via FTP, 'DRMDecrypt_x64_TEST.exe' works fine for SD (576i) and HD (720p). 1080i not tested yet.

Using the GUI i have exact the same symptoms as Spoza:

Just a partial success here...
Movielisting now works fine (more or less... I see one strange character in one of the titles, but I don't have any details yet to report), but clicking Download button in the movielist window has still the same effect - "preparing download" window opens with the "...please wait..." message apeearing for a second or two and then both windows close and I'm back in the main window.
Trying to process a file manually downloaded to a local folder freezes the application during the decryption process and at the end it crashes.

so the only thing working is listing of the recorded movies.
The GUI is nice, and it would be even nicer with all functions working

Ok,

hopefully, it is now fixed...

I implemented the Adaption Field Fix as well as some bugfixing in the FTP Download function. (and corrected the spelling error).
I also uploaded a binary 7z archive for those who do not want to use the installer.
Again, sorry guys that I have to use you as guinea pigs...

FTP didn't work for me but no need to FTP access.
I copied PVR files with "UFS Explorer" and then decryped .srf files with your program and it works for me.
Thank you very much my friend.

Just a short note - it's actually ADAPTATION field, not adoption field... using correct terminology helps understanding each other

Now the decrypting is working for me. I use the method in Denny's first post. It's a bit painful, but doesn't matter. At least now I know I can save my recordings to blu-ray disk!

I even tried it, tsmuxer accepts ******.ts and you can make it to AVCHD or blu-ray. Then burn it to UDF2.5 and PS3 accepts it. Next step for me is learn to convert .ts subtitles to blu-ray subtitles, but that's another story...

Thank you Denny!

What is painful there? Speed? If it is issuing the commands there are some possibilities with scripts

I know Sisternicky has done good scripts, but I use linux. As I'm not good at programming, I do it harder way. I'm used to it...

@Ilkku,

actually, the scripts are originaly from Denny, I just ported them to .NET and put them into a nice gui.

PS: You might be able to run it under Wine. I have not tried it yet. Unfortunatly, Mono does not recognize WPF that good, so there is no possibility for a native compilation.

PPS: There is a new version of DeSTRoi on the way that should get rid of some nasty bugs. It is in the final testing phase now (thanks @Spoza) and I'll upload it when I get the green light from him .

great, looking forward to the new version, the last one doesn't work for me - "preparing download" and then bang and nothing...

I made some studying with hex editor:

mdb1:
00000000 01 00 00 00 00 20 00 00 AD E7 E8 FA 07 49 DF DD
00000010 24 7C 9C 50 42 D3 05 FD 00 00 00 00 00 00 00 00
key1:
00000000 FA E8 E7 AD DD DF 49 07 50 9C 7C 24 FD 05 D3 42

mdb2:
00000000 01 00 00 00 00 20 00 00 A8 2A 60 37 9A FA 60 91
00000010 B2 AE 3C 44 F0 4C 4F B3 00 00 00 00 00 00 00 00
key2:
00000000 37 60 2A A8 91 60 FA 9A 44 3C AE B2 B3 4F 4C F0

mdb3:
00000000 01 00 00 00 00 20 00 00 D7 83 39 1C D6 2A 74 29
00000010 D4 CC AC 0E A8 B6 E9 0E 00 00 00 00 00 00 00 00
key3:
00000000 1C 39 83 D7 29 74 2A D6 0E AC CC D4 0E E9 B6 A8

Three different mdb-files and drm.key-files. As merilix discovered, there is pattern in the mdb files. I even tried manually edit new drm.key file with data of .mdb and it works.
Does this pattern differ from your merilix, or why can I get your code work?

My TV is UE46D6507 and firmware is T-GASDEUC-1018.0

Finally I got it right.

Tested and working (hopefully for everyone now). I'd like to thank Spoza especially for helping me test my changes.
Here they are:

-- Fixed multithreading environment that caused some unexpected and weired things to happen
-- Improved memory usage. This should help to prevent performance degredation while running the program
-- Fixed some localization issues
-- Automated column width so that they do not cut off their content by default
-- Added merilix' Adaption Field fix, adjustable for each single file to convert and controlled by a central switch
-- Shows stats by default now
-- Fixed a crash bug when canceling download

hope you guys can use the program well . As everytime, if you have any suggestions or discover any bugs, don't hesitate to pm me.
