I just got a new Sony LCD TV for my den. I also purchased a new Denon receiver and got a PS3 for Christmas. I have a DISH network HD DVR. My question is: Should I run the HD DVR through the reciever and then to the TV via a HDMI cable? What about the PS3? I can figure out the speakers okay but I'm trying to figure out how to get the best picture and sound out of my new equipment. Thanks.
