LE 8.90.2/.3 Alpha Mecool K3 pro tvheadend problem

First of all thank you for the 8.90.3 build. It's running great on my Mecool K3 pro box. However, I have a small problem with tvheadend. The one of the repo works perfectly for FTA. However, when inserting a CA line, tvheadend keeps restarting on non-FTA transmissions. When using the tvheadend version of found in the K3 pro thread, this works perfectly fine but introduces another problem: Recordings can be started (and work well). However, when ending the recording LE still thinkgs that recording is going on (red point, indication in TV menu and so on). Ending the recording again will open a pop up saying that recording cannot be ended and logs should be checked. Logs do not contain anything useful. So I guess its either a problem with tvheadend server or client. Any ides on that?
