David, Through previous posts, I believe you have a Sony STRD-825 (same as me). I also think you use a Go-Video for games, causing you to use up one of those video inputs. Here is my set up, hope it helps you.

Video 1; DBS
Video 2; VCR
DVD/LD; DVD
TV/DBS; TV audio
Tape/MD; Cassette deck
CD; Comp Disc
Tuner; OTA antenna
Phono; n/a

In the event that I purchase another component and am in need of an additional input, I will (vinyl proponents, please don't be offended) use the Phono inputs.

Contrary to your opinion, I think there is a lot of good surround enhnaced network programming that should be distributed through your system. Good luck, Dennis!
