OPPO OPDV971H Digital HD-Ready Up-Converting DVD Player
If you have the Infocus 4805 pick this up
I had been playing DVD's on my x-box.  I got tired of the space it took up and the feeling of an inferior picture.  I was lucky enough to catch this player on sale at Amazon (which is A LOT slimmer).  I have it hooked up to my Infocus 4805 via the DVI out.  It is amazing.  I know most people would be hesitant to shell out $200 for a DVD with HD-DVD's on the way.  However, think to yourself about if you'll be hanging onto your DVD collection.  If you are do yourself a favor and pick this up.  It will offer the chance to rediscover you entire DVD collection which is worth a lot more than $200 in my opinion.  One other comment is I have a 6.1 surrond sound system powered by a Onkyo receiver.  I don't know if this is possible but it seems like the sound is even better with this DVD player.
