Made a fresh install after SD Card issues this morning.
I will bury my dvbviewer/Mediaserver PC now. TvHeadend on K1 pro and Digibit R1 satip-axe will do the job now.
Four different HD Streams without problems. NICE!
There is only one little issue : K1 pro Audio is connected with my Pioneer VSX AVR via HDMI.
Sometimes Audio in live tv is partly scrambled when starting live tv. Stop/start solves it.
If you have a genuine hardware related issue like this then it would be great if you could post it on the GitHub issues page so a solution can be found in an organised manner, posting on the forums with not even so much as a log will mean your issue will remain and never be fixed.
