Dear all,

I have setup a TVheadend server. It is a Intel NUC on Debian 11 and I use a Hauppauge dualHD stick. I want to receive DVB-C from Unitymedia in Frankfurt.

The scan for stations went well, EPG reception is working as well. However, when I want to capture or view a station (e.g. via VLC), I get only some chirpy signal and the webinterface indicates under Status a ton of Continuity errors for the particular station (see screenshot).

These are the erorr messages in the web gui:

The Linux kernel is 5.10.0-11-amd64 and Tvheadend version 4.3-2009~g1295dd2be

Can you give me any idea?
