If you are experiencing problems with DVB processing, missing services, incorrectly reported service types, etc.. Then a mux dump is the most useful tool to allow developers to investigate the problem.
To obtain a mux dump you should find the Play link in the Mux configuration tab:
Copy and Paste the URL and use something like curl to obtain a short sample:
curl -m 30 https://xxx/stream/mux/65d799bce51d49df83d367c29006f744 > sample.ts
This will capture a 30 second sample from the specified multiplex. This will only work if your card supports raw mux reception (most modern cards do, but not all). Also if you have access control on your TVH web interface, then you will also need to specify this.
