My TV has a ps3 via HDMI, 360, Wii, Xbox via Component.
Gamecube, N64, SNES, NES, Dreamcast, Saturn, Genesis/32X/Sega CD, Master System, TG16, 3do, Neo Geo, Jaguar, Laserdisc player plugged into two automatic AV selectors. One of the AV selectors has Y adapters in each input making it accept 8 systems. The two outputs from the two AV selectors go into the back of my DVD recorder again with Y cables. Then the output from DVDr goes into the TV input. So I can record gameplay of anything at the touch of a button. All the Power cords are plugged into Power Squids which I personally find to be hideous but super functional.
