Why make it easy when you can make it hard?

When you need the encryption key for 20111109131508.srf, just look at offset 8 within 20111109131508.mdb.
Its there :)

just change source of drmdecrypt.c to read drm_key from mdb file:
...
// try .mdb
sprintf(outfile,"%s",argv[1]);
sprintf(&outfile[strlen(outfile)-3],"mdb");
if((outputfp = fopen(outfile, "rb"))){
fseek(outputfp, 8, SEEK_SET);
for (j = 0; j<0x10; j++)
// read each byte separately because of different byte order
fread(&drm_key[(j&0xc)+(3-(j&3))], sizeof(unsigned char), 1, outputfp);
fclose(outputfp);
} else {
printf("Cannot open %s key file\n", outfile);
return 0;
}
...

This way you can decrypt your recordings even if you don't have full SamyGo access to the TV where they are recorded.

Hi
I have a Samsung TV UHDUE40KU6472.
I recorded something in a HDD drive NTFS formated from TV and found everything in CONTENT folder inside of HDD. There are few files, among them a .srf and a .mdb perfectly readable in my PC. I try read between topics and get lost. I arrived here somehow and reading this I was happy thinking it will be easy.
I try DRMDecrypt_x64, DRMDecrypt_Win32 from the last which include even the code from up and having also .mdb file I have got the .ts file with conversion OK using both, but always .ts file is not recognized by any player. I tried VLC or media player. :(
I was thinking having that .mdb file no need the key. Can I convert and make playable the .ts file with DRMDecrypt as is described up?
It's no clear for me how to get that key. Do I need the key?

Thanks in advance
Samsung UHDUE40KU6472

You need root AND key :)
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on http://ctrlv.it/ Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!
DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!
