I've just purchased and installed pdvd 15 ultra on my pc using Windows 7. I've tried to play two dvds and the playback is jumpy and the voice dubbing is out of sync. I've cleaned both dvds, though both are brand new and the problems were still there, I've also played both on Windows Media Centre and encountered no problems!
Any ideas of what I can do? I'm a bit disappointed as I had an earlier version which worked wonderfully.
