How to play a dvd from a Mac G4 on a television?



I have got the new G4 500 with a DVD ram but I can't get to play a dvd on my tv.
What is the output on the computer, is it a firewire?
If so, how do I connect it to the S-video input on my tv?

Is sound also sent along through the firewire?

If you have any clue please let me know.
