If you TV doesn't have an S-Video out or an RCA video out, then you can use a VGA to S-video adapter, a VGA to RCA adapter, or VGA to S-Video/RCA adapter. Then you can use an S-Video + RCA cables just an RCA cable.

You can also use Xbox 360 S-Video AV Cable like DreamLine S-Video/AV Cable for Xbox 360, but it can transfer optical audio only.

It seems to be pretty complicated, so you may want to ask other people.
