Looks like I got this part wrong.  When I play old MJPEG files on the
host machine, the lines are visible.  When I play then on a frontend on
a different machine, they are not.  It appears that somehow the PVR-250
is interfering with playback of old files, even though it has nothing
whatsoever to do with them.

Ideas on this weird problem would be most welcome! :-)
