I'll do this, thanks for the good suggestion. Do you have a suggestion as to
what might be the best source material? I tend to like things with talking
heads and static graphics like CNN to do comparisons as the scenes are

The tuner results in worse results. Sadly, to get S-Video I have to order HD
service from Comcast as their straight digital boxes available around here
do not have it. Of course if I do that then all my questions will be about

To a certain extent my expectations are somewhat skewed by my experiences
with what I was using prior to getting a Myth setup. My Pioneer DVR-520H-S
used the exact same input, cable and all, from my STB and produced much
better results. This is another reason why I don't think there is anything
wrong with the composite output (relatively speaking, of course) of the STB.

I just signed up and will lurk for a bit just to see what goes on on that
