1080i is an interlaced format (that what the "i" stands for). What
you describe sounds like a progressive display trying to deal with
the interlace and doing a poor job of it. Which output of your nVidia
card are you using (VGA or SVIDEO/Composite)? Does it look OK with 720p?
I know pcHDTV suggests using xine for playback, and I notice that's
not one that you mentioned.
I've had good luck with 720p HD video but around here we have only
one digital OA channel and they don't transmit 1080i very often.
Maybe I'll stay up late and check it out when "Letterman" airs in
