How do I configure my TV's A/V input jacks (red,yellow,white) so I don't have to switch cords to watch a DVD?

My Sony TV only has one set of imput jacks (red, yellow, and white) in the back of it. I have a Tivo hooked up to them now, but if I want to watch a DVD, I have to switch the cords. Is there any device I can purchase to eliminate this hle?
