Fairly common problem, most TV encoders are trying to do progressive to
interlaced conversions and not neccecarily doing a great job of it. The
video doesn't always line up with the scan lines, and conversion between
the two is ugly, so the whole thing gets a bit soft.

And the original content was interlaced, so you've really got
interlaced->progressive->interlaced in there.

One of the drivers I have for getting a decent HD set is not really all
that HD content out there, but so I can drive it over HDMI in a
progressive mode and bypass a few conversion steps.
