Since I got a new television set I have problem with hum with RTV. Other
inputs to the TV (a dvd player and a DishNetwork PVR) don't hum.
However, the RTV does. The hookup is S video and RCA cables for audio.

Any suggestions for this low-tech question?

It could be a poorly shielded cable. Replace the cables (one at a time
to see what works).

Also, try different outputs from the Replay and inputs to the TV (if
is has more than one). The Replay does have duplicate audio outputs,
so you can try both.

Note that using an RF connection produces definately lower quality,
and should not be used unless you have to.

Depending on the combination of products you probably have a ground loop
problem. Try a Radio Shack Ground Loop Isolator (#270-054) which
replaces or extends the RCA cable between the TV and the RTV. It's
almost certain to fix your problem. I once had to use one between a VCR
and a receiver and it solved the problem completely without affecting
audio quality.

A grounfd loop is a possible cause of this problem, but you could save
some money if you checked the cables first.

Step 1 is to make sure beyond any doubt you have those RCA bacles hooked
up right, Plugging a video cable into an audio jack on the TV end, or an
audio cable into the video jack on the RTV end causes just that kind of
problem... VERY LOUD

Step 2 is try a NEW set of audio cables as a broken shield (Ground) on
one of them can cause that kind of problem

Step 2b: is re-route the cables.... If it makes a difference then get
new cables, only this time buy good ones
