Why even replace it if we can strip it off?  Myth knows how to handle 
automatically adding the black bars during playback if the aspect ratio
of the video doesn't match the aspect ratio of the display.  So, strip the
black bars off and change the 4:3 or 16:9 aspect ratio to the correct
aspect ratio and let the playback code handle the black bars as it already
does.  If you watch a 4:3 video in a non-4:3 window on a 4:3 screen, the
display code will even add in black bars there because it knows the
window is 4:3 but the video isn't.
