Deinterlacing was already off which is probably why I can see some of the
interlacing issues, though having it on or off doesn't really change the
choppiness.  Before I was using it on a monitor with deinterlacing on.

I think with my current settings the tv tuner nor MythTV are doing any extra
post-processing.  With the flicker filter off through nvtv and my resolution
settings at 640x480, I don't think the card is attempting any rescaling or
cleanup to attempt to make things like text more readable.  My hope is that
with these settings every other line written to the screen by MythTV
corresponds exactly to a line on a field of the video, so that the tv can
smoothly display the interlaced video stream as it was originally recorded.

Note that the choppyness isn't *that* noticable except with things like
tickers.  It's fairly acceptable otherwise, though I can see it's a tad off.
Has you or anyone else been having more success with the smoothness of the
video to the point where thing like news tickers look perfectly smooth?
