AFAIK the burning program built into XP does not finalize the DVD, so that you can record more onto it. Great if it is going to be used on another computer. Some DVD players will play the thing without it being finalized ( I admit that after many years of doing this I still do not know exactly what happens at the physical file level when a disk is finalized) And why some devices finalize in seconds and others take 20 minutes.
The client's DVD Recorder knows about finalized versus not finalized and is thrown for a look expecting its own version of an open project. I have seen the same thing if you move an open DVD project from one brand of recorder to another
I have never found any way to force XP to finalize.
Thus the suggestion to buy Nero of any of the Sonic DVD burning programs. $50 at best buy.
Or use DVD+RW media which does not need finalizing, but older players, and again recorders that do not do RW ( don't have the RW logo) will choke.
