I currently have 1 622 feeding a tv in my living room and my bedroom. I would like to add another 622 or 722 to feed two more tv's. However, I would like the tv1 output to feed video via hdmi to a television in a different room than where the new box would be installed, and then split the tv2 signal to feed the tv in the room the box would be installed and a tv in my kids' room. That may be a little confusing, but here's my question: Can I have two RF remotes controlling the same box at the same time, 1 to control tv1 and the other to control tv2? Would I need to purchase another remote, or can both remotes that come with the receiver run in RF mode? Let me know if I didn't explain the setup very well.
