Unable to provide support for DVB's - they will either work or not - I'm not about to go digging in DVB drivers.
Improvement are unlikely to come until the AML S9xx gets complete mainline Linux Kernel support sometime this year.
That gives some reason for hope, thank you.
Unfortunately that's not an option. HEVC is a nightmare with tvheadend 4.0 (or kodi < 17.0?).Numerous (non HEVC) TvHeadend users get better results using TvHeadend V4.0
