I just replaced cables, that didnt help. I swapped the cable ports on my wall and that didnt help. So, now I know its not the cabling. Its either the BBC's or one of the tuners. I swapped BBC's to the cable cable/tuner input, still no difference. So, I know both BBC's are good as well. When I only leave tuner #1 hooked up in the back of the box, the show plays. When I only leave tuner #2 hooked up, I get frozen video and no sound. THat leads me to believe tuner #2 is bad in the box. Thoughts?
Also, I have a Slimline dish running to a 4x8 multiswitch. HR21 (the problem receiver) in my man cave, HR20 in the family room and 2 SD Directivo boxes in bedrooms.
