This looks over 3 years old, which may or may not be the cause
Also, you could try using -ovc copy, if you already have JPEG
there's no need to convert to JPEG once more.
There's a chance that it then crashes when you try to play the
file, but since MPlayer is better maintained than mencoder that
might still count as progress...
