Generic-tvheadend42-4.1-2116 with Silicon Labs Si2168 : DVB-C #0 errors

    Hi,
    I fresh installed LibreELEC-Generic.x86_64-7.0.1 with Generic-tvheadend42-4.1-2116 and I run into a problem with my usb Silicon Labs Si2168 : DVB-C tuner.
    It's recognised by TVheadend oke, but when I use it I get loads of errors like this when tuning to a channel:

    2016-06-10 22:29:44.786 cat: 570.75MHz in ziggo: invalid checksum (len 42, errors 78)

    2016-06-10 22:29:45.030 parser: transport stream H264, DTS discontinuity. DTS = -961582131, last = 11520000
    2016-06-10 22:29:45.057 parser: transport stream H264, DTS discontinuity. DTS = 11523600, last = -961582131
    etc, etc

    When I plug in my Sundtek dvb-c tuner and enable it directly starts to work without any errors.

    When I use the Silicon Labs Si2168 DVB-C tuner with my previous install of Openelec 6.0.3 and TVHeadend 4.1 on the same machine they work oke.

    Anyone any suggestions to make it work? Is this a driver issue?

    Edit: same problem with TVHeadend 4.0.9 from Libreelec repo.

    Thanks in advance!
