Default Earth loop somewhere- humming sound

Hi,

I couldn't find any better Newsgroup to ask this question.
It's about a TV antenna.
When I try to capture a video from a VCR (the VCR is connected to the
antenna), I get a humming audio signal.
When I unplug the aerial cable, it's gone.
The antenna is installed on the roof and is proper earthed. In between
is a booster. I don't know if the booster causes the trouble but it
shouldn't.

The humming sound is only there when the VCR is connected to the PC (via
firewire) and the aerial cable is plugged into the VCR.

Any tips how to solve the problem would be greatly appreciated.
