Ok I think I may know the answer to this but I didn't want to make any purchases before I got some advice from the masses, but I have an OLD TV. It's a Mitsubishi that looks like it's from the 80s (probably is) and the only jack in the back is one to screw in a cable cord to. But I have a DVD player (philips, with audio in, coaxial jacks and everything, but no screw on plugs or anything like that) and a super nintendo that I would like to be able to run whenever I want from the back of my TV.

I've heard something about an RF modulator or anything like that... but what do you think I need in order to hook up my DVD player (at least, i can manage not plugging in my super nintendo, but I would PREFER to.)

If anyone could help me at all, that would be a huge huge help. Thanks a bunch all!
