Hi, I need to start looking for a new receiver. I watch a lot of DVD's and HD shows. I want the receiver do all of the video switching. I use KRK Rokit studio speakers for my 5.1 system and have a Velodyne sub. I have a Denon DVD 2200 and a Panasonic 47x54. My budget is $500-$800 for a receiver. I'm thinking of Pioneer, Yamaha, or a Denon. What should I look into? Thanks!!
