I have gone to houses where the power ground broken off and it was using the cable for grounding purposes...It is always intresting to see 50 VAC feeding on the sheild. Nothing like this though. I think a complete rewire of lines would be the LEAST they could do.. heh. Unplug your cable boxes at night...
