Hi Formuler Staff,
The Z11 list all Groups channels 1, 2, 3, 4, 5, 6, 7, and so on for each category. I also have the Z10 which doesn't do it with the same provider.
If channel is not working properly, it may numbered 20 on the Z11, when the provider has it as channel 125 for example.
I hope I have explained it properly.
