Thanks a lot. This seems to have worked. dvdauthor accepted the mpeg
and I made the ISO. I just need to get home from work to put a DVD in
the drive and burn it. Thanks.
A note for anyone else reading this, when it makes stream.yuv, it is a
gigantic file. A 3 meg AVI will turn into about 300 meg yuv file. I
guess this might depend on bitrate and stuff though.
