I thought I would kick off this thread with some positive news. I want to thank drieschel for the work on the S802 builds!!
I can confirm that this is running on an M8S+ which I upgraded from a working OE 6.95.1.1 kerber build
LE is much better! I have never been able to watch live TV video from a usb tuner with OE and with this LE build running TVheadend - I now have the most affordable pvr in the world.
I will note that it took a few restarts to get running. The IR remote is not working (I have an RF MX3 so no worries there) and I sometimes don't get a clean boot. It could be due to my box having to have pins shorted while working with different firmware, but when it does boot it is running well.
Since the IR does work from the kerber build, drieschel you could look into his source for any differences: GitHub - surkovalex/OpenELEC.tv at openelec-6.0
One other note - not specific to this build - the tvheadend 4.2 addon is still missing the ATSC predefined muxes. This was being looked into in the past but I haven't seen any updates on it. The versions at index - powered by h5ai v0.29.0 (https://larsjung.de/h5ai/) have this issues as well (tested on Rpi3)
Thanks again for the great work on this release. I'll continue testing and encourage others with working OE builds to jump in on the upgrade to LE!!
