Hi all, I'm a newbie too and am thinking of buying a receiver around $400 that satisfies the following needs. First of all, I have to ask a newbie question that's been bothering me. 1) What does a digital output on a receiver do? Is that for pre-amps? As for the right receiver, I need to connect the following: 1) DVD – Sony DVP – S530D 2) VCR – Panasonic PV-8662 3) Digital Cable Box 4) Xbox ( I really want to use the Optical digital input for Dolby Digital playback) and hardest of all, 5) I'm not currently buying a speaker system, rather using my computer and it's speakers (fairly nice THX speakers but nonetheless, still computer speakers). From what I'm guessing, I need at least 3 digital inputs (DVD, Cable, Xbox)? and what do I need for the computer??? The choices I've narrowed it down to are Denon 1802, Onkyo SR600/700 Pioneer 811S, H/K AVR 225. Help!! Thanks so much.
