Summary: 

We have a cable hook up with two boxes, one for the VCR and one for the TV.
And a switch that selects whether the TV shows the TV Cable box, or the VCR
signal (which in turn may be either the VCR Cable box -- or the VCR output,
depending on whether the VCR is switched to TV or VCR).  VCR output can
either be the VCR's demodulation of the Cable signal, its tuning of a
regular station (if I've switched its input from Cable box to antenna), or
a VCR tape.

The TV receives the Cable fine.
The VCR sends the Cable directly fine (when switched onto TV)
The VCR broadcasts tapes fine.
The VCR broadcasts antenna signals fine.

BUT...sometimes when the VCR taping/rebroadcasting a Cable signal (when
switched onto VCR), there's a loathsome hissing noise.  The better the
picture, the worse the noise.  Turning off the TV and VCR AFC switches
helps a little.  The noise is most intense on the VCR's bulletin board
channel with lettering...or when there are subtitles.

What can be causing this?
Any suggestions for what to do about it?
Thanks in advance.
