If you're not locked into that particular model, you may want to check out the Pelican System Selector Pro. It's marketed at the videogame market, but it has some pretty good features. I just bought one of these at GameStop for $79 but have not hooked it up yet. EBGames and newegg.com sell it for the same price. It offers 8 inputs for composite, S-Video and component video. Also 3 of the 8 inputs support optical audio and ethernet. Here it is
at newegg. It is not remote controllable, but I figure if I'm switching between satellite, DVD and games I'll have to get up anyway to grab a controller or put in a disc.
Good luck.
