Hi Howard,

I have run in to the same hum problem here, but its not a ground loop as all
of my audio and video equipment are plugged in to the same surge protector.
I have found that if I use an S video cable between our TV and cable box
that this cable causes a slight hum on the audio circuits even though I'm
using good quality cables.  If I go back to a standard RCA jack video cable,
the hum is gone. My Wife tells me that the s-video cable gives a slightly
better picture, but it also causes a little hum in the audio amp too.  So, I
am fortunate that the hum is at a very low level and would probably not be
noticed by most people.

Take my advice, I don't use it anyway.

I have a ground loop somewhere in my house.  You know how boring that
is to find, and how expensive it is to pay someone else to find it.
Well it gets hum in to the tv audio outputs in to the amplifier and
speaker systems, that I use for that purpose.
So do any of you know where to find an audible polarity checker that
I can plug in to each of mmy outlets until I find the problem?
How fun!!!
