anyone have any experience with the Sima SVS-4 audio/video switch box? I ahve one that works great until summer when AC is one. I get all kinds of interference on my tv. If I bypass the switchbox the tv is fine so I know its the SIma box that is picking up the interference. Anyone have any suggestions I can try to eliminate this other than an expensive power manager?
