My friendly local video delear (Hi Tech Video) sells both Beta and LaserDisc.
He claims the 20 per cent improvement in resolution provided by Super-Beta
is noticeable, but nothing to get excited about.  It still isn't anywhere
near the same league as LaserDisc n respect to picture quality.  In additon,
the sound quality on prerecorded tapes usually isn't as good as on LaserDisc
because of the extra generations involved.

SuperBeta increases the center frequency of the video FM signal by about
1 mHz, allowing for a bit more bandwidth in the Y channel.  The I and Q
signals are still hetrodyned to a low freqnency narrow bandpass channel.

If you have a two piece VCR, you might be able to replace the tuner portion
with one that received the MTS signals.  It might also be possible to add
MTS decoding to your present tuner.

When the local PBS affiliate goes stereo, I plan to look into just such a
conversion myself.  From what I have read about MTS brodcasting standards,
you might wish to listen to an MTS stereo broadcast before deciding to
spend the money to decode them to stereo.
