I use a Psyclone PSC-01 for my analog video and audio switching. The unit can do component, S-Video, composite, and even TOSLink optical digital audio and RJ-45 network switching. It is a 4 X 1 device. They are relatively expensive new, but can be had much cheaper on E-Bay. These are full-featured switches, and include remote control capability as well as programmable labels for each input with a backlit LCD display that shows which device is being switched.
