Radio Shack sells a cable intended just for this sort of connection.
I believe it's called a "Mini phone plug to RCA attenuating cable".
It's the appropriate cable to use to connect the headphone out of your
TV to the Line In (or Aux, or Tape In) plug on your stereo.

P.S. My first Mac (long gone now), which was a very early unit, had a
RCA connector where the mini phone plug is on the current Mac.  It even
cut the sound to the internal speaker when you plugged something in!
The signal levels, however, were the same as the current Mac.
