I don't know what you mean by that.  If you playback a 4/3 video with
"-noaspect" on any Nvidia/ATI cards with TV-out, it will look just as
squished on the TV as it would on a monitor.

If you were here, I could show you what I'm seeing first hand.  Since
you're not, you'll probably have to take my word for it.  The 60fps
video playback is rather jumpy, and any fine details (straight lines,
glasses, pinstripes, etc) get pretty well chewed-up.  I can easily watch
the actual channel, then flip over and watch mplayer's damaged output of
the same segment.  Even someone with poor eyesight could tell you
there's a problem.

Yes, I know.  I tried each of tfields=[0-4], and I even tried each with/
without inverse telecining.  No improvement (not that I was expecting
any).

We can certainly agree on that.
