Summary: Hifi VCRs do have noise reduction. Well, sort of...


Hi,

1.  To the best of my knowledge, no comsumer grade VCR has a
modulator that can create an MTS signal.  The MTS modulation is
very much akin to creating an FM multiplex signal.  This is rather
expensive, especially since the TV MTS uses dbx encoding on the L-R
part of the signal.  Also, most stereo monitor/TVs have audio line
jacks any way.  (I know the VCR is in the living room and the TV is
in the bedroom, oh well...)

2.  Both VHS-Hifi and Beta Hifi use companders on the Hifi tracks.
True, the formula is not as complicated as dbx or dolby.

3.  Some VCRs do indeed have the capacity to decode dolby-ized
video tapes.  Mitsubishi makes one, I'm sure there are others too.

4.  Several boxes are around:  NEC AV-300, Sony, Yammaha that can
recover the dolby surround-sound signals.  On a decently done tape,
the effect can be pretty neat, although, I'm not sure if you'd call
it audiophile!
