I am having a problem with the 630 remote interacting with another receiver. I have the 630 in our main living room and then in the basement I have my regular HD receiver. I have noticed over the last few days that the remote for the 630 interacts with the reg HD receiver in the basement while we are using it on the 630 upstairs. It somehow is creating timers, changing channels, turning it on and off etc on the reg HD receiver. Is there a way to change the 630 remote frequency or something so it won't so this?
