Thanks, Henk. My encoding command currently uses "-of mpeg -mpegopts
format=dvd:tsaf". I substituted "-of rawvideo" for that and everything seems
to work the way I had hoped it would, without adding your command as an
additional step. Is that OK, or do I risk problems by using "-of rawvideo"
instead of "-of mpeg"?

Also, do I risk problems making a DVD by ignoring dvdauthor's warning that
the 24 fps frame rate of the input file is incorrect?

Thanks again.
