i'm having a strange problem. every time i try to burn or copy a video dvd with nero, the drive and nero lock up at the "100% writing lead-out" phase. when this happens, i cannot close nero, cannot eject the disc and cannot stop the drive through the windows "safely remove hardwar" utillity (it's an external drive). i have to shut down or restart the PC completely to get the disc out, but the disc will be complete and will play in my home dvd-player. this does not happen when burning data dvd's. anyone have any idea what's going on? thanks.
