I knew you guys would have all the answers. The smoothness is a bit jarring
and kind of makes me motion sick. It reminds me of old videotaped stuff,
only a lot sharper.

So, theoretically, an uncompressed rip of a Blu-ray disc played back on my
Mythbox should look identical to the same Blu-ray content played on a
Blu-ray player? The PC input on the tv is VGA, not DVI. I assume that
switching from VGA to HDMI would result in a better picture?
