The reason the picture quality looks so horrible via SVGA on your
PVR-350 is because SVGA is progressive scan whereas your over-the-air
stuff is interlaced.
When hooked via the VGA port, you're essentially displaying on it as if
it were a computer monitor, and you will get the best possible picture
Via S-Video, you are limited to a 480i picture, which is fine for
regular TV images, but everything else (DVD's, HD content) could look so
much better. :)
One of the ways to display the 480i TV content on your nice high-def
screen is to enable the checkbox for "de-interlace video" and select
"Bob (2x framerate)". This will have your Myth box work a little
harder, but it will essentially "upconvert" your normal 480i content to
progressive. The results won't be fantastic since you are limited by
the quality of your source (in other words: upconverting can only do so
much), but it should look between good and very good. :)
