[mythtv-users] Electrical power in my cable line? Is that bad?

[Dan Wilga]

In addition to what the other posters said, you should also not rule 
out the possibility that the fault is in your house's *electrical* 
wiring. If the computer is plugged-into an outlet (or powerstrip) 
that is not properly grounded, there could very easily be a 
difference in potential between it and a cable TV wire--even a 
properly-grounded cable TV wire.

Just having a 3-prong outlet at the wall does not always mean that 
third prong is connected to anything. If in doubt, you can pick up a 
tester cheaply at any Radio Shack or home improvement store.
