No, Martin, my problem is not being able to burn, at all.

I think I may be one step closer to solving the problem in that I have determined that my burner seems NOT to be recognized by either PS8 or WMP. In PS8, all the burn options are grayed out, and, in WMP the burner is not listed in the drop-down of places to copy/send the file (I know this won't make a disk that'll play on anything but another computer). And, in Windows Explorer, when I click on the burner in the left hand column, I get an error message saying the drive 'is not accessible-incorrect function'. This is when there is a blank DVD disk in the drive. When there's a written disk in there (as, say, a program installation disk) it acts normally. This burner is an external USB Pacific Digital that I've never burned a DVD from before.

Does this new wrinkle suggest anything to all your fertile minds? I hope so :( :-) :(
