The biggest prob. I have is having to unistall the UltraDMA on my Sony DVD drive after "succesfully" burning a disc. Once I go through that process, all of a sudden the blank disc magically becomes a movie title and is playable. It would be nice to not have to uninstall/reboot every time, but it works.
The error 400 is actuallly the first time I've seen an error dialog box in about 20 or so attempts, so I figure it was the movie disc. I'll try again and get more info. I think you guys are doing pretty damned good work!!
