NO NO NO NO NO!!!
DO NOT GET THE HD931!!!
1st of all, the hd931 is a steaming pile of poo. Its of dubious build quality and has a major flaw.
Its color space or more correctly its gamma is tuned to the pc standard for dvi. The video output from the dvi incorrectly throws out information below a certain level of black.
This is called balck-clipping. In essence it will simply leave out alot of shadow detail in low light scenes, causing it to look like a muddy mess.
rear projection lcd already has a hard time with blacks and shadow detail hence, you do not want this player.
I have the 50in sony we610 with a momitsu v880 dvd player.
This player outputs dvi with either 720p, 1080i or a vareity of custom resolutions that has been released for it via fw updates and ones u can create yourself.
This upconversion, (the player upcoverts the native 480i signal on the dvd to any of the high res formats) and subsequent delivery via dvi leads to a great dvd picture.
On fixed panel tvs like lcd and dlp (lcos as well), dvi is almost a necessity to get the highest quality picture.
The sony lcd tvs, though have a great internal scaler and do not benefit so much with these types of player. So the sony tv would be fine with a good 480i dvd player.
However, I have tested 480i/480p players and the dvi upconverting players side by side, and there is a perceptable improvement with the dvi player, especially with fine detail.
This is much more dramatic on dlp based tvs. On my sisters samsung dlp set, the dvi player is an absolute necessity.
momitsu v880
also if u do have your heart set on a samsung dvi dvd player, the 941 should be here very soon. We'll see how good that thing is.
