First of thank you so much for helping. I've tried to search to fix my problem, but I could not find any solution

Few months ago my TV's mainboard has broken and I had to change it. Now there is a new in my tv.
But I had many recordings on my external USB drive and now I can not replay them

Do you have any idea how can I remove the DRM protection? I could open the files, over Linux operation system, and tried to decode the file with Destroi 1.3.1 which decoded the files to TS but I can not open them. I tried with many players, but nothing happened.
The other hand I tried DRMdecrypt.exe in CMD, but it result was the same

I would appreciate it if you could help me.
All the best,
Vilmos
