Actually, you're right on the mark. I guess a little better explanation is in order. Currently, we have a non-HD setup with two DVRs. They set side by side. We'll call them "his" and "hers" for obvious reasons. Overlapping programs dictate that we have two recorders. She watches reality TV, soppy movies, ongoing programs etc. He (that would be me) watches History Channel, Football, Racing (F-1), Discovery Channel and a few movies.
With the setup we have now, we use RF receiver/transmitters to "shoot" the signals into the computer room, bedroom, and sewing room and either DVR can connect to the "big" TV via the surround sound receiver.
We can't afford a new surround sound receiver at present (gotta save up for April 15th) and for HD we need a hardwire connection. "His" will be hardwired to the "big" TV and also to the bedroom TV. "Hers" will be hardwired to the "big" TV and both will still use the RF "shooters" to shoot the signals into the computer and family rooms where we don't need and can't use an HD signal.
Thanks to this thread, I now know that the HD DVRs have both HDMI and component outputs which takes care of hardwiring to two different TVs and also composit outputs which will take care of the "shooters". Now the only problem is to find a long enough component cable to get to the bedroom before the installer gets here on Sunday.
