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

That is exactly what happened to me.
The previous owners had installed 3 prong outlets but didn't bother to hook up the ground.
I was getting a nasty jolt every time I unsrewed the cable.
I put a multimeter on it and found 45 volts coming across.
Needless to say I replaced the outlet. :-)

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.
