I used to have a problem like this as well, some things to check, is
the hum in the recording or the playback? If it is in the recording
try hooking the rf out from the cablebox into the tv card, even if you
aren't using this. I had a cable box/apartment with some weird
grounding problem, and that was the easiest fix I found for it.
