I've searched and searched for my problem in your forum and haven't had any luck.  My dilemma:  Getting a clear - not snowy - picture of my Dishnetwork channels.  I can get clear crisp pictures of local channels via a regular antenna - the HD channels are superb!!  When I go to watch regular satellite dish channels (Dishnetwork) they are snowy, fuzzy, etc.  Anyone know why?  Am I missing something simple?  I've tried hooking the cable back up to a TV and the picture is fine.  I'm using the latest of PCTV software for VISTA.  Help please.  Thanks!
