In my new PC, I put in an AverMedia Stereo TV Tuner Card and have found that several channels have enough interference so as to make them nearly unwatchable. Other channels look pristine, so I don't think the card is the issue. The "fine tune" function offered in the card's set-up menu does little to fix things. In my previous PC (233 Mhz PII used until this weekend), there was an ATI tuner card that worked great... all channels were the same high quality. My new PC is in the same location as my old one, so all the connections and distances to the card are the same. I'm wondering if any type of line amplifier may help. Any thoughts?
