I tried it with several 8.x builds and alexelec and on all it is the same problem.
when i start "deluxe music sd" on european astra satellite and then i cycle through the miniepg channel list with the up/down button and after some seconds box freezes and 30 seconds later it just reboots.
Settings/PVR & Live TV/Playback "Confirm channel switches by pressing "OK" is ENABLED so it doesnt switch to the channel!
Is the addon damaged?
I dont have this with coreelec but since coreelec isnt stable i want to go back to a 8.x build but with this problem now ...
