In order for there to be an inexpensive adapter to composite or S-Video
(which is just a separated version of the signals combined in
"composite"), the Mac needs to provide analog video -- RGB, usually.
If the Mac uses a mini-DVI port, the analog signals are (probably)
present; for mini-DisplayPort, they are not.
If all you have for starters is digital signals (i.e. mini-DisplayPort),
the conversion is still possible but a lot more complicated. There are
external boxes that do the job, but they cost somewhat more than a small
"adapter".
For inexpensive versions of either, check eBay. I've gotten mini-DVI to
composite adapters there for a few dollars, though in one case the first
didn't work and I had to convince them to send a replacement.
