As I stated in my original post the files are from Videowave, but they are just photos from a SLR camera--very very simple. This is not a complex question. I wanted to know what the message is saying, becasue it is not documented, and no one seems to be able to explain it. The reply from ROXIO was silly, because if they really read my note, they would have seen that I had already tried to make an ISO rather than go directly to the burn. I have been doing videos in Videowave for probably 15 years - long before it was part of ROXIO. This is a software problem and an undocumented error. I don't think the requested hardware information is relevant to the problem, but at a high level I have two machines, a home built one with an I7 2600 processor, 8 GB ram and a DELL I5 with 6 GB ram. Both run W7 home 64bit and neither have video cards.
