Thanks CA Guy,
My system includes a Russound whole house audio system that allows me to use the Tivo audio as one source, and also use the Russound's IR repeating capability to control the Tivo box from any room. I actually started out years ago when I installed this system with a D* receiver used only for satellite music as one audio source, along with tuners and CD changers. To make it easier to select the correct audio channel on the D* receiver, I plugged a TV into the RF output of the D* box. Worked fine, so I plugged it into the existing cable TV coax system already in place throughout the house. Although the PQ is not great, it works fine for the five or six 27" CRT TVs in several rooms in the house. The four 50" and 58" plasmas and the CRT PJ in the theater all have their own HDTivos.
The logic behind using composite over coax comes from my plans to upgrade all receivers to the MPEG-4 DVRs soon. I plan to also replace the SD tivo that feeds my Russound system with a new D* DVR with the non-Tivo GUI, so all DVRs use the same interface. (WAF.) The new D* SD DVRs do not have a RF output, so I'll need to use composite video (or something else) instead. My idea was to use the existing coax throughout the house for composite distribution, instead of pulling new wiring.
It appears that I can use a video ditribution amplifier to accomplish this. I've found a few on eBay that apear to meet my needs. I tried to find a local source for the video dist amps, so I could return them easily if they don't work for me. I've tried CC, BB and Fry's, but no luck. Rat Shack is next on my list, then fleabay.
Thanks to all for your help. I'll return to this post with results so others may learn from my experiences.
I'm finding that I'm smarter than I thought, but dumber than I need to be.
