I bought the unit used. Sometimes it plays OK, then sometimes it plays for a long time then the video usually freezes, but the timer on the front of the unit keeps counting. Pressing track forward or back usually doesn't do anything.
I updated to 4.0 firmware and it seemed to help on some discs, but now I was playing 300 and the unit froze up twice in two different spots. The discs look clean.
Any fix for this?
