Yes, mplayer plays the source files (the original mjpeg mov's) perfectly.
Im having problem with mencoder converting these mjpeg mov's to a
different format due to the variable framerate they use.
It seems im missing options that mencoder needs to be able to
duplicate missing frames so that the output video is properly sync'ed.
