I had posted the following in another topic, because it sounded similar, but I did not get an answer, so I will try and post as its own topic:
Is there a limit to the number of channels shown in the guide?
Here is what I am experiencing with a mix of 2 HDHR Duals (via Antenna), 1 HDHR Prime (via CableCard) and Spectrum's TVE:
On all of my Fire TV Stick 4Ks:
When I make the Prime a higher priority than TVE, I am missing a several channels, in the Guide, from TVE.
When I make TVE a higher priority than the Prime, I am missing several channels, in the Guide, from the Prime.
It doesn't matter where I have the Duals prioritized or if I turn one of the Duals off, as all the antenna channels show in the Guide.
Non-Hidden Channels: 41 from Antenna, 78 from CableCard and 109 from TVE. Total of 228
When Prime is Priority 1: 41 from Antenna, 78 from CableCard and 62 from TVE. Total of 183
When TVE is Priority 1: 41 from Antenna, 34 from CableCard and 109 from TVE. Total of 184
So, is there a cap around 183 or 184?
One other note: The free TVE channels (above 6700) only show a difference of 1 in the two scenarios above (43 when Prime is Priority and 44 when TVE is Priority).
