You should probably just be happy with digital 480P. Fact is, most upconverting DVD players can only offer a marginal improvement over the standard 480P output of a good progressive scan DVD player. Spending what could potentially be $1000's of dollars to upconvert doesn't seem like very good bang for the $ but you asked for it.
I'm sure there are others but I've never tried any of them. As with anything in this arena you usually get what you paid for so beware. _________________
