Connecting Macbook Pro to TV via S-Video or Composite video

Hi,

I own a Macbook Pro mid 2010 model, and I was wanting to connect it to my somewhat old TV. The TV itself has a input for S-video and the regular RCA composite inputs, no HDMI, VGA, or DVI. I purchased a miniDisplay Port to DVI adapter and a DVI to Video Adapter. I tried to get it to work but to my dismay it didn't because the number of pins between the 2 adapters were different (something about DVI-I and DVI-D). But although I am not too happy about wasting my money I still want to connect my macbook to my TV. Is there anyway I can get that to happen? I also have to miniDisplay port to VGA adapter if that makes a difference.

Thanks,
Teague
