I'm using a ChannelPlus 5545 on internal wire and I love it. I have the DVD, VCR, BUD and DVB connected to the 4 inputs, and use channels 65, 70, 75, 80 as the outputs. It's frequency-agile so you can put the channels anywhere you want them. Easier for me to pull wire, and I'm using 2.4 GHz for computer network, and 900 MHz for cordless phones.
I use a regular 75-ohm splitter "backwards" (3db insertion loss, but -75db between my signal and the outside world) signal goes out to 6 TVs, anybody can watch any device independent of any other.
It keeps the kids happy. The TV in the living room watches the "line in" for quality, but when I want to watch the end of the late-late show in the bedroom, it's on ch 65 anytime. No AC-3, but the 15" TV in our room is mono anyhow...
