For movies it is hard to tell, the 1080i up converter is extreemly
good. You don't have to believe me, that's fine, untill I got this set
and saw the picture for myself I wouldn't have believed it (Hitachi
51F500 is the set in question). I've had two other HDTV models to
compare it against (an RCA and a JVC). On live HD content (non-film
transfer) HD quality shines though, but we're talking about DVD and
movies (almost all of which originate from film sources anyway).

The set is very capable, find a dealer in your area that carries
Hitachi HDTVs (rear-projection) any model will do since they all share
the same 1080i up conversion technology, have the sales rep put in a
DVD for you and then compare what you're seeing on this set to
everything else (all the other sets on the floor. If the DVD player is
just an average mid-grade model (something that cost less than say
$800), even the Pioneer Elite and Mitsubishi Diamond models will pale
in comparison. It's not that the technology in the other sets is poor,
it's just they don't have up converters built in. Almost all the other
manufactuers have chosen to make the upconverter an extenral add-on
(for example, I believe Pioneer provides this in some of their Elite
series DVD players). HD quality will produce different results.
I don't know if Hitachi's up conversion technology is propritary, but
the only other DVD quality look this good is when the signal is
proceed though a Faroudja chip. As mentioned, I went though two other
HDTV sets before coming to this one, I had the same DVD player
connected using the same component cables...
