For Christmas I received a new capture card. It's the Hauppauge WinTV-HVR-1800. So far it seems to be a pretty good card. I'm just having one problem though. I've watched shows with it in Media Center, BeyondTV and VLC, but they all seem to be a little grainy/snowy. I have the cable straight from the wall to the card, so it's not going thru any other sources or connectors. Any ideas what may be causing the picture to be grainy/snowy? I've included a pic below to show how the video looks. Thanks for any help anyone can give. :)
