SVGA.. definitely.

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 
that way.

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. :)
