I made some new images for mvr9, posted on freaktab forum.
There are some default settings already set and bluetooth is enabled by default.
I see in the tvh addon v4.4 they had a fix for videos buffering, freezing and increased the cache, maybe that can help. I will try to build tvh v4.4 if it can't be installed manually, how do you install the other versions?
thanks, will try your build
I took tvh 4.2 from le repo and tvh 4.3 builds from here Tvheadend nightly builds for LibreELEC, but as mentioned there was no difference in behavior.
