After a lot of help from Henk Shoneveld and some help from a few others, I
found it necessary to use ffmpeg and MP4Box to clean the video, then ffmpeg
or MEncoder to remux. I was making a different conversion, maybe you can use
some of what I did to help with yours. You shouldn't have to follow my
pullup method or encoding options, I think.
