I need some advice for a cheap ground loop isolator/filter. Seems I'm getting some hum from my DVD player. Everything is plugged into 1 circuit and in phase so that's not it. Probably got a plug(s) wired backwards somewhere in the house. I'm not really inclined to go through all the wiring to find it if I don't have to.
Any help would be appreciated.
