SGTFlipFlop Sky Bouquet Question

[Thameswater]

hi, im using one of the latest bouquets where the sky numbers are in the top favouritte group followed by other groups underneath.

question is

can i delete all the other groups and leave the sky numbering group by itself?

also, when i press the program up or down button the write up says it should just skip to the next channel even if theres a gap between channels, but i dont get that, i get "service unavailable, check tuner configuration"

is there any way to fix this?

thanks and thanks
