I don't rememer the brand of the TVs, but they were hooked up via HDMI, and both players set to the native res of the TV, which was 720p. I didn't bother switching to 1080i; I couldn't imagine it would improve the pq doing so. I asked the salesguy to take out the demo disc (took forever on the HD-DVD player to do so), and to put in an actual hi-def movie disc. The Blu-Ray was playing House of Flying Daggers, and it really did look exactly like an upconverted DVD. The HD-DVD was playing . . . Chronicles of Riddick? Something. Darnit, I can't remember which movie it was. Anyway, same story.
I remember seeing the benchmark for the HD-DVD player. It was based on its upconversion of DVDs, which was only average at best, if I recall correctly. This current generation of hi-def players just don't do DVDs justice compared to the really good DVD players out there, as MACCA said. But that may change soon with the next generation of hi-def players.
Now if Denon were to make a hi-def player . . . oooh, that'd be shiny!
