I don't know if anyone else has noticed this but when pressing the 'PREV' button the EPG changes to a bouquet list in grid and multi EPG.
Pressing the 'NEXT' button acts as expected and scrolls through the bouquets.
This is on a fresh flash of ViX 5.3.033 with no settings or plugins restore and just scanned for Freesat and imported EPG.
I haven't changed any button designations but I am using a 3rd party remote.
I'm not complaining about it. I think it's a better feature than just scrolling through the bouquets one at a time and I would like to replicate it on my other boxes.
I can scroll through the bouquet list and just press 'OK' to go to that bouquet in the respective EPG.
It is the same in any skin.
