To the best of my knowledge the MythTV implementation of the Nuppel
Video Format lacks an internal index ... and seeking in mplayer and
your divx player probably are expecting an index to seek on.  I use
avidemux to add an index and wrap the file with an avi container, and
have had no problems with the output.

/usr/bin/avidemux --load ${filename} --rebuild-index --output-format
AVI --save ${filename}.avi --quit

In theory you should be able to use mencoder with the forceidx command
as well, but I can't vouch for it working for every file.

mencoder -forceidx -ovc copy -oac copy -o <out_file> <in_file>

Hope this helps,
