It's interesting that I'm getting NW Cable News (a DCII signal) on C4 while all the scrambled DCII channels on that bird shows "Can't find channel". I've tried adjusting azimuth and polarity with the 4D control but can't get the "Subscription required" to display. This is happening on G0 also. HSN and QVC on C4 display good though. So, any idea of what's causing this problem?
