I got one "1 duplicate frame(s)!" with and without harddup, but that
shouldn't hurt?

However, can you dvdauthor the resulting stream without errors? My
dvdauthor complains:

Same thing with harddup. Audio works until the playback freezes. Looks
pretty much the same as previous tries without audio.

If I extract audio and video from video_me256_0bf.mpg with tcextract,
multiplex with mplex and then dvdauthor - no problems. Playback on
standalone works too.
