Some Words of Advice on DVD Receivers
Until about a year ago, I was using JVC RX-DV31SL which I'd definately recommend if you are going to go with a DVD receiver. It lists for $450 but you can get it way under that new online or even less used on Ebay. This receiver plays DVD-A and you don't need to get 6 additional cables because of the way it is integrated to play DVD-A. It integrates everything excellently and I used it with my Orb 5.1 Mod 1 System which Orb recommended. I thought the sound was very good with the Orbs. This system sounded better to me then alot of high end seperate DVD players & receivers.
Here's the thing though. Through trial and error, I bought a seperate DVD player (Harmon Kardon 31) & a seperate Denon Receiver (3801) & the difference in sound was significant for DVD's, CDs & TV. If sound quality is of major importance too you, I'd go with a seperate DVD player & receiver which spacially really won't be much difference, just make sure you do notice a difference in sound. The one thing I don't buy is the argument, well what if your DVD player portion of it breaks down- the chances are slim of that happening and if it does you can either connect another DVD player through it, get it fixed or buy another system.
