Tsee,
I'm having the same problem, but I believe that the cable companies signals are bad. I still haven't been able to fix this problem (since Sept 2005).
I'm moving soon so I'll find out if it's my cable provider or not.
I just got a TV tuner card, but channels 2-9 on cable input look fuzzy even as most, but not all, other channels look better than on my 25" TV. I'm wondering if this has to do w. the lower resolutions on TV sets, anti-piracy protection, or what. Thanks a lot.
