I'm having enormous amount of Continuity Errors with Hauppauge WinTV-dualHD on Ubuntu 18.04 Server running as VirtualBox guest. I'm getting around 20 000 Continuity Errors in couple of minutes and can't see a single proper frame. Usually the playback is not starting at all on VLC. Then everything works just nicely on OSMC on Raspberry Pi. I would prefer running Tvheadend on that Ubuntu though as it is easier to arrange large disk, fast network and reasonable performance for it. Actually I'm not even thinking Tvheadend is the problem as I'm not able to get the picture on another Ubuntu 18.04 Desktop with Kaffeine player either. However, by searching I see that others have had similar issues.
Where I should start investigating and what to try in order to get that Ubuntu work with Tvheadend and my tuner properly? I wonder is the problem with VirtualBox or software installed by following Hauppauge guide. Somehow I'm feeling it is some driver or other software issue as everything works out of the box with OSMC and not with Ubuntu by following Hauppauge guidance.
What I have tried so far.
- Using same cables with each setup and also shorter cables.
- Several reboots and other USB ports.

At least the firmware seems to be the same on different setups. I also compared the actual files.
[ 10.879394] si2168 4-0067: downloading firmware from file 'dvb-demod-si2168-b40-01.fw'
[ 14.880338] si2168 4-0067: firmware version: B 4.0.11
[ 14.979566] si2157 6-0063: found a 'Silicon Labs Si2157-A30'
[ 15.083108] si2157 6-0063: firmware version: 3.0.5
Usually getting around these values so signal should be fine.
SNR 37 dB
Signal Strength -30 dBm
