To see if this is a "burn" or recording issue I'll let Ulead create the files needed for the DVD and then use CDBURNERXP (free and found with google.com) to place the files on the DVD recordable media. I might use ISO 1 or ISO 2 and a closed session to make it very compatible with DVD players that accept recordable media.

I'll also record at a speed less than the media's rated speed.

No cure, but what I would do.
