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

Sure - just take a multimeter, set it to DC voltage in the 10V range, 
touch one end of the probe to the metal screw on the coax cable, and 
stick the other end in the 3rd prong (ground) of the outlet you plug 
your computer into.  You should get zero volts if everything is 
properly grounded.

Make the multimeter more sensitive (set it to the 0.1V range) and 
repeat.  If you get zero volts (or close to it) at the most sensitive 
setting, then you should be good to go.
