I know the feeling. :-\

Cool.

Oh, I forgot. ProSavage8=ProSavageDDR (my boards is an MSI w/a KM266

Huh. My experience hasn't been anywhere near as good as yours (with the

True, no interlacing, but I have found their output pretty good... I'm 
not actually using a TV output anymore, but rather a GF4MX (onboard

adapter, with a progressive-scan signal to a High-Def set.
