I found the Fine Tune in the server GUI to adjust things.
But i guess i misunderstood how the feature works.
It seems to be just anohter On Now like page, but for on later, that can be tweaked to include or exclude certain categories and channels.
I added just one Preferred channel, but it still shows programs from all other channels.
I gues u also have to exclude channels to else the default is show all channels.
EDIT: I am also getting erratic guide scrolling behavior now with the highlighted block disappearing and the screen not scrolling. Now that the channel cells are useable, its seems to jump around a bit now.
EDIT 2: For sure, the guide will NOT scroll up or down at all if i am highlighted the channel number box section. It will only scroll down if a program block is selected
