Here is my own little modification of Dennys nice tool compiled with VS2010 as Win32 and x64.

To use it, just drag/drop filename.srf over DRMDecrypt_x64.exe (or DRMDecrypt_Win32.exe).

If filename.mdb is present in the same directory, it will read the key from there.
Otherwise it will try to read the key from filename.key. Default output is filename.ts.

@Spoza: viewtopic.php?p=25252#p25252 improvements are now included.
Im not sure why decryption will not work for you.
drmdecrypt.exe will normally decrypt each valid TS frame where encryption flag is set.
I also cant speak about ftp issues, i use samba on TV and "net use V: "\\192.168.1.101\Samsung TV"
on my Windows 7 PC to mount my TV as drive -- works very well :)

Hello,

does this method work with Samsung UE64ES6300? Can I decode .srf ?

Just to know anybody had trouble with the file decrypted with DRMDecrypter? I have this problem it seems he decrypt all files present in my portable hard disk but there are some that with i.e. Media player don't show any video nor any audio. Other are perfect. The problem is that I have cecked with Mediainfo and they don't have any codec difference. I try to check with GSpot and GraphStudionext64 and they are perfectly performed with audio and video!!!!
Anybody has suggestion? I cannot convert in a valid format.

Hello, I found a bug in the latest versions of the tool posted: it crashes with a corrupted file.
The problem is that the check on corrupted content must be done before removing scrambling bits.
I fixed the problem and attached to this post you can find the compiled binaries and the source code.
Enjoy! :D

P.S. It's compiled with VS2013

Dear SamyGo community,
I hope this post still helps people struggling with drmdecrypt.
- I'm using this version of drmdecrypt: https://github.com/decke/drmdecrypt
- I use it on Ubuntu 14.04.
- The Samsung TV is a UE37D6510. I did not root it or use SamyGo on it because this version of drmdecrypt claims reading and using the key out of the MDB file.
- I used the -d parameter to get debug output - it says:

INFO AES-NI CPU support disabled
INFO drm key sucessfully read from filename.mds
INFO KEY: the key...........
INFO writing to newfilename.ts
INFO Filesize -1
INFO synced at offset 0
INFO short read while reading stream

The output is a .ts file the same size (about 9 gig) as the .srf file.
Problem is - it won't play in VLC and is not able to be converted via handbrake. Handbrake can not read the file - it is stuck while analyzing it.

To check if the srf files are not corrupt or something like that, I used destroi on a windows machine. It worked perfectly - the ts file was able to be played via VLC or converted via handbrake. Sadly, destroi is no option because of the windows machine is not present the whole time. Decryption and conversion has be done on the linux machine.

I hope you guys can help me out on this - I would be really happy and appreciate your help.

Many thanks and best regards
Muhackl

Nope. Don't want to hack the firmware of my TV. Bet, there is another solution. But thanks.
