You will need to go to the apple store and buy an adapter that will plug into your monitor port. You have only described analog inputs though which means it won't look great and even if you had digital i'm not sure the macbook integrated graphics would be able to handle it
It will look like crap through Svideo. Unlike erickkoch, I would rather have decent resolution than a couple more inches. But for $19 you can get the Svideo adapter for your Mac at the Apple Store. It should be called "Mini-DVI to Video" or something like that. Do a search online or ask at a Store.
Are you sure the TV doesn't have an HDMI or DVI port? Or VGA? Seems really strange that it would not have one of these 3 choices if it is a recent model.
