When I create a video project with Movie Maker and then try to burn the DVD
with DVD Maker, the program gets to about 98% done, then the disk ejects and
I get a message that says the DVD couldn't be burned. I have tried at least
20 times and only two attempts were completely successful. A few tries
partially burned the DVD and a couple burned DVDs that wouldn't play on this
Vista computer or the DVD player attached to the TV - but they would play on
my laptop with XP and an older version of Media Player. I have tried
different brands of DVDs, different write speeds, and reset the filters to
the defaults. Does anyone have any suggestions for what else I can do? Thanks.
