When watching TV on my PC using AverTV Studio I can see vertical noise lines. This does not seem to be a weak signal problem, but an interference problem. I tested an older Pinnacle PCTV Rave card on the same PC and I could see the same thing, so it's not a card-specific problem. I also tried a different cable/antenna and again I had the same issue. Moving the TV card in a different PCI slot also did not help. Anyone has any ideas on how I could solve this problem?
