I am interested in buying a HD reciever for my new Samsung 507 because the SD brodcast sucks. I have dish network which I will have to remain with for a while longer. My current dish box is a PVR 508 which I like except for the fact it is not HD. Now my question is what to buy to best utilize the HD capabilities of my new tv. I have been looking at the dish 6000 and the sammy sir-t165. One of my questions is if I run the dish signal through the back of the sir-t165 will it improve the SD signal by upconverting it to 720p? We watch a lot of dvd's and local channels, but there are a few shows on the dish the my wife cant do with out. Any suggestions? Oh one thing that I like is the fact that I can hook everything to the sir-t165 and have one input to the tv through the dvi input.
