256kHz?? Do you actually have an audio card capable of playing this?
44.1kHz is fine for what you're doing. First, make sure your audio is
at a sane frequency.
Try forcing the frames per second with -ofps=29.97. Or try creating
an OGM file instead (my personal recommendation). You can encode the
video in MPlayer into an AVI file (just use -oac copy), encode the
audio with oggenc, and then use ogmmerge to create an OGM file from
the .avi and the .ogg files. As long as the lengths of both the audio
and the video tracks are the same, the audio packets should be
interleaved just fine with the video frames. OGM has double overhead
(headers for the OGM packets and headers for the OGG frames), but it
doesn't have the braindead index-at-the-end-of-the-file problem that
AVI suffers from, and you win back that overhead with the space
savings of the Vorbis codec.
Oh, and consider using XviD instead of DivX. That way you can truly
be free. :-)
