Now that we have three TVs in the house, I need to buy at least one more DTV receiver to keep everyone happy. When I first signed up for DirecTV, I bought the higher-end RCA unit with Dolby 5.1 output with bigger TV sets in mind. However, we all know that DTV just doesn't look that great on large TV sets. Are any DTV receivers better than others when it comes to decoding the satellite signal? I was thinking about just buying the cheapest decoder I can find with S-video for my new Panny, and using the RCA unit for the other two. The RCA unit has RF remote functionality, which makes it very attractive as a multi-TV receiver.
