7 Home premium 64 bit. How to connect to tv w/ card

I'm willing to purchase a graphics card. I tried to buy a converter on ebay but it didn't work so i guess i have to purchase a pci card. I'd like a recommendation.

I have two tvs, i'd like to use RCA cause both tvs have it.

I know cards have multi ports and 1 tv has rca and s video one tv only has rca.
I can run audio from the computer.

I'd like to be able to run a movie on the tvs, or share the monitors desk top with the tvs.
I'd like to be able to use my computer while the tvs run the movie.

IN the past, what was on the computer monitor would be on the tv in xp. eventually i learned how to expand the desk top. That was xp. In 7 i can't do anything. The old cards don't work, the signal converter off ebay didn't work and i think now that i finished one project. Its time to tackle this nonsense.

Do either of the TV's have VGA or HDMI?

no. both have rca out, one has svideo

I"m going to put a dvd player on one to see if it will cover both tvs like the cable does. Wishful thinking though. I don't expect it to work.

The only option is to get an adapter that converts from VGA or S-Video to RCA. Only two that I know of that have it off the top of my head. If that doesn't work with the computer then get a card that supports it.

i hooked up an old dvd player and was able to get that to split to both tvs. So now i can use my computer while the tv is a double screen. I'll just have to rip avi to dvds. Its cool with me i guess. thanks
