Thanks again. No splitters with the destacker. I did detach the antennae connection and reset the satellite on the unit. Transponder 18 no longer registers, so that must have been some sort of late night anomaly. Still, no right side of 101(A) the unit states, so no functionality. If you think it helpful, I can also go into the closet and get the names and types of stackers and in line amps and splitter that are used on the way to my units wiring. When I looked last night, they were wide band splitters. What also is odd is that the Sony B-50 worked fine win the set up, so I am not really sure what the HD DVR is sensing that is different. In the meantime, I will open up the wall and see if there is a non-wideband splitter used to feed the second cable connection internal to my unit somewhere in the signal path.
