My guess is that the two different outputs are running at slightly
different refresh rates, such that the HDMI cable uses some refresh
that's >2x the video frame rate and the VGA doesn't. Therefore, when
you play video on the HDMI output, Myth chooses to use your primary
deinterlacer--my guess being that it's bob--and when you use VGA it uses
a fallback.
Turn off bob deinterlacing. IMHO, you should just plain set the
playback profile group to the default configuration of Slim.
