Reddit reviews BIRUGEAR RCA Audio Video Switch Box Selector Splitter (6 Input 1 Output) for Game Consoles, DVD Players, RCA Players, Digital Camcorders etc

Looks like you need one of these.

I have not found a bad one yet, but I did a fair bit of research on the matter before buying them.


For S-Video/Composite I picked up a couple of these.

For Component I picked up two of these mostly due to optical audio support, but later stopped using optical since I didn't have any PS2/Xbox games that really benefited from it. Made cable management a bit easier too.

I bought this guy last week, it seems to work, haven't tried all the s-video ports yet: http://www.amazon.com/gp/product/B0031IIXW0/

I use this for connecting my NES/SNES/Dreamcast/Gamecube/PS2/Genesis to the TV. It saves so much clutter and I can flow and strap all the cables to one area. The TV doesn't have enough plugs for all of them anyway, so a switch is a must.
