I'm at work at the moment and a student is having problems with some DVD-Rs that he recorded on a Bush VHS/DVD Recorder combi from Argos. (He recorded VHS to DVD-R) He forgot to finalise them but they play OK on the Bush. However, they also won't play on any of the PC DVD ROM/Writer here at work even though they are failry new drives. I would have thought that un-finalised DVD-Rs should play OK on PC Drives. Question is... Before I taks his discs away with me tonight to try them out at home, do they need to be finalised on his Bush Combi before they can play on a DVD-Rom etc?
