I have a similar problem, for me the big difference was switching TVH to use matroska, but the seeking issue still occasionally happens, but it is tolerable now
What version of TVH are you using for your backend? is it containerised?
I'm on one of the 4.3 nightlies, but i'm thinking if its worth switching back to 4.2 stable

Hi, If anyone cares/experience same problem, it seems LE version 10.0.3 solves this issue.
I meant that the .TS recording is now o.k (works like on PC librelec/windows kodi) and seeking backward works.
I stopped using matroska container since it caused more problems overall.
