I have a question for everyone I just purchased an hr21 from BB to replace an old RCA receiver I am going to move up to HD service from D..tv and I am going to buy the next HD receiver from them to get the free dish install. My problem is I have an old R10 that I want to keep in the setup and an old hughes for a tv that is not hd. I want to put the new Hr21 on my new flat screen but also keep the R10 connected. When the installer puts in the dish am I going to be able to still use the R10 or will it not be compatible with new dish and will I have enough connections from the new dish to have both hr21s the R10 and the old hughes receiver still connected.
