I currently have a 510 and a 301 system. I got my system a couple of months before I got my tax refund, so I couldn't afford the HDTV-in-a-Box system at the time. I now have the RCA D34W20, which I believe is the same TV you get with the system anyway (I got mine in February for about $900). I want to add the 811 (hopefully with the latest firmware) and take out the 301. I would really like to keep the 511 also connected to my HDTV for recording programs (the DVD 921 is out of the question). My assumption would be to have a second line run to my living room (for the 811), and connect a wireless A/V transmitter to the 510 and send the signal to where the 301 is now (In the bedroom). I believe there would be a way to set the receivers so that the remote controls would not interfere with one another (in the living room). Am I correct in all this? Thanks in advance.
