Well, I finally spent almost an entire day getting the 6200 to
"somewhat" work.  on TVOut, I can get a perfect 480p picture.  On TVOut
@ 1080i, (only with 8178 drivers) it works, but I get flicker on bottom
1/3 of screen still with bad overscan.  With VGA->component, I get a
"stable" 1080i picture.  Myth menus look perfect, but the desktop is
quite fuzzy - probably due to font sizes, etc though.

My new problem is that when I go to display ripped DVDs (I still do not
have 6200's to play with - only RCA-DTC1000 which is incompatible with
anything) X locks up instantly.  Even with all of the setting mentioned
here.  I get about 1 second of audio, and then nothing.  Have to Ctrl-C
the xserver and restart it.  I have not configured xvmc yet, as I just
wanted to get xv going 1st.  It is a fast enough machine to chew it, so
CPU I will work on after video.

I had to change to HD1080i

This option makes no difference in 8178 - even through nvidia-settings
it does not show up.

Had to use TV-0 before it would recognize it, but that was obvious from
xorg logs.

Thanks for the info -
