TF6000PVR recordings transfer for DVD

[voyo]

Hello,

I wanted to transfer my recordings to my PC via USB but I have a problem with files
- recorded encrypted programs with green padlock symbol (fully decrypted on Topfield which can be watched even without the viewing card in the receiver) cannot be opened and edited on PC.
Any recorded free-to-air programs are OK to edit on PC.

Is it normal for decrypted programs?
Can it be fixed / edited?

Bitte hilfe.
Danke schoen.

Voyo
