That dreaded hum

Hello all, I hope I'm in the right place and my question is what can I do to get rid of a ground loop hum in my rig. The particulars: I have my audio and video hooked together and when I want to watch dvds I have to disconnect my cable from the wall to eliminate the hum. I know Mondial used to make a box for this problem but that was many moons ago. I thank you in advance and happy Memorial day.

South,

Richard Gray's Power Company makes products just for that purpose. Take a look at their Pig Pole especially.

You can still buy the Mondial at "Music Direct" for $99 but there are lots of examples of these isolators. This is the cheapest I've seen:

Cheap fix is to go to Radioshack pick up a 75 Ohm to 300 Ohm adapter,and a 300 ohm to 75 ohm adapter ,connect them together
& hook it up to your incoming cable before your components,this will eliminate your hum & should cost about $11.00.
