Jesse,
My problem is indeed the blocks random of colors in the middle of the screen
that cover the picture, plus pausing and hesitating.  It does not happen
when playing the signal through my cable box, so I assumed it's not a signal
problem, BUT ... my cable provider did tell me at one point that my signal
was "less than perfect" so ... is it possible that the HDTV-5500 requires a
better signal than what the cable box does?

Anyway, I will try to tweak the other settings, and see if that helps.

Let me take this opportunity to say **thanks*** to everyone on this board
for your willingness to share your knowledge ... I must have solved dozens
of issues by searching the mailing list archives (even if many messages are
about hardware and technically "off topic" viz. mythtv itself,  they are
still incredibly helpful) and y'all are great.

Mary
