I'm using Xfinity with an HD Prime and which a lot of channels are duplicated (i.e. Channel 105 and 1005 are the same.
When I go to tuner sources and Line up, I see channel 105 on the left and on the right, i see 1005. If I try to remap to 105, it acts like 105 doesn't exist.
However if I look at the Channel Guide, I'm seeing channel 105 in the list and the current shows.
Why would the lineup show 105 mapping to 1005 and not 105?
