I recorded some shows for my son on Cartoon Network, and this afternoon I tried to play them on his PC and I keep getting a message that it is copy protected and I can only play the recording on the PC in which it was recorded. So I decided to try some other shows that were recorded and none of them played either. But I've never had this problem before with his PC. Both the HTPC and his PC are running Windows 7. Does this sound like a PlayReady issue? I tried uninstalling PlayReady and reinstalling but that didn't help. Any thoughts?
Edit: Oh yeah, the recordings are made with an HVR-1600 through S-Video from satellite receiver.
