Fortunately, the information about cable not being able to carry MTS TV
stations has been a myth.  But, there are conditions.  1) The cable company
must use IF type receivers and not baseband receivers, at the head end.
2) Any cable converter used (if any) must also be of the IF type, not
baseband type.  The headend IF receiver is the receiver that is used to pick
up the TV signal off the air and convert it to the cable channel needed.
If the cable company gets the video/audio directly from the tv station,
you will not get stereo, until a unit is put into place to get the stereo
to the cable company and the cable company spends the money to put in the
extra equipment required to put MTS on the channel.  Our cable company is
just like that.  We get direct feeds from the stations involved (2 of them).
One we get off the air, for now.  The other, because the headend is so close
to the station, makes antenna pick-up a little rough.  But, both tv stations
have plans to work with the cable company and help pick up the expense of
getting the required equipment to get MTS on the cable channel, using direct
feed.

Now, in your case, I think that channel 4 is giving you trouble because
you are receiving tv channel 4 on cable channel 4.  Not good.  What you
will get is cable channel 4 and some of the off the air channel 4.  MTS
is very picky about its signal.  Mixing two of them out of phase will
cause problems.  You will have to bitch at the cable company to move the
channel around, ie, put cable channel 4 somewhere else.

Hope this helps a little bit.
