When I first got my DTivo box a couple years ago, I was excited and ran the cable in a very lazy manner, outside across the roof, down along house and then drilled into behind TV. Finaly now with the diplexing out of the picture and just being sick of looking at the tacky cable up there, I decided to move it correctly. Its just not the easiest thing to do in my living room due to vaulted ceilings. At any rate I finally did it and have 2 seperate sat lines and one for OTA. When I began this whole deal both sat tuners worked, except for the new HD's on Tuner 2 where I had a diplexer on it sharing the line with OTA. Now however, Tuner 2 is dead! It is not the cable, not the dish/multiswitch, or BBC. If I swap cables it still works fine in Tuner 1, and nothing on Tuner 2. What could have happened to cause this? I have tried resetting, and re doing the setup numerous times with no luck. Both OTA tuners and St tuner 1 are fine. Am I S.O.L here? Could trying the BBC before the diplexer "trick" had anything to do with this? Did I do something wrong hen I moved it? Coincidence?
