Is there a way to hide channels in EPG that do not have data on them? I have a few providers that have decent EPG but some channels they just do not have the data. Is there a way to hide all of these at once in PP?
There is no such automatic feature (as it’s very strange feature).
However, you can use “Groups management mode” to move some channels into groups and hide some groups (“Hide group” item in channels list context menu).
