    Hi Girls&Guys!

    I found a Bug, which breaks HW-decoding of TV-channels under CoreElec 9.2.2
    (full discussion of the issue and logs/samples can be found here: https://discourse.coreelec.org/t/tvheadend-choppy/10574/23)

    VERDICT >> FOUND the issue-maker: as soon as an EXTERNAL USB-GRABBER is activated in Hyperion.NG, the stutering / choppiness starts (fushicai utv001, not plugged in!).
    ==> Deactivating the external grabber instantly fixes the TV-channels not being decoded in hardware!

    Now - to the solution ?

    Another Take:

    - Clean install of CoreElec 9.2.4.2
    - Clean install of Hyperion.NG addon
    - Clean install of TVHeadend Server + Client + Oscam.
    (Did NOT copy ANY files from a backup)

    - Configured it ALL from Scratch!

    --> activated USB-Grabber with prio 230 ( internal grabber is 250/default)

    after 3rd reboot, video-device for decoding TV is not available and only SW-decoding is available, which renders all CPUs to 100% !
