Whomever installed your cable never bothered to ground it properly.
Your choices are to have them come back and do it correctly or ground
it yourself if you know what you're doing. Sadly, it happens more
often than you would think. Someone mentioned not long ago that they
fried their motherboard by plugging the firewire cable from their
ungrounded set-top box into their machine. I nearly blew up my
PVR-350 when I first got it because of the same problem. The tip is
still a little black, but surprisingly records just fine. :)
