I have a similar story. I used to have a backend in my basement so I
wouldn't have to hear a machine running 24 hours a day. Then when I
got OTA high-def happening, I couldn't put the antenna(s) in the
basement, so I set up a slave in the livingroom to capture high-def.
This also had the advantage of recording and playing back high-def in
the livingroom and recording the (much more frequent) standard def
stuff in the basement.
