The basic situation is this:  the stereo information on TV signals
(MTS) is provided as supersonic information in the audio signal.  The
audio range for the stereo information is from about 15 KHz to about
50 KHz.  I'm sure you've noticed that the audio response of your
average TV and VCR is sadly lacking even in the audible range, so
there's no way you're going to get a 50 KHz frequency response on any
set which wasn't intended for MTS stereo.

There are at least two brands of MTS stereo "tuners" that you can
connect to your stereo system.  Radio Shack sells one, and a number
of stereo/TV stores sell one made by Recoton.  These connect to your
TV antenna (*not* cable TV, few cable systems provide 50 KHz audio)
and to your stereo amplifier.  They have a tuning knob to select the
channel.  Unfortunately, the reports I've heard about both have been
less than enthusiastic.
