Setting up my 1st home theater system and confused on a/v recievers, want something for 5.1 thx? (front ,center rear,s.w.) also to use as steroe, and see ones that say they upcovert video, some say to composite,svideo,hdmi,etc. can someone tell what to look for or links that explain. Recomendations on what to gett for under$1000 for reciver,have speakers and dvd/cd player. Some models talk about all kinds of zones you can set up,dont need to be that fancy,just good theater sound and upconversion if that works Thanks, Roy
