I have recorded on 4 dics. 2 in video mode and 2 in VR. Only one of the "video" will play on my PC. The DVD drive says the others are empty . Op system is XP pro. What I have noticed is that only this disc can be unfinalised.The other 3 can not (or finalized which I had already done)). I can play all 4 on the AV mode in my TV via the camcorder drive.
