High bandwith at one tuner
Three identical usb tuners TBS5580 are used.
On one of them very high bandwith during epg grab and at usual viewing of channels (screenshots 1,2). I guess this has become a problem of a lot of transport and continuity errors when watching TV (screenshots 3).
With the other two, this has never been observed.

If the 3 cards are the exactly the same and the other 2 behave normally, the issue is probably a faulty card and not related to tvheadend...
But... can you post a screenshot of one of the another cards (#0 or #3) tuning the same mux as card #1 (example: 11920V / MTC) ?
The last image shows "pid list" set to "all". That is the reason for the high bandwidth. I assume you did the obvious of checking the configuration of all adapters and making sure there is no difference? Check the "maximum pids" settings. You can try to un-check the "Allow all PIDs" setting and see what happens. It may fail in this case, but then we would have to see why tvheadend thinks the maximum pids have been reached and it is trying for all...

Interestingly, some channels have almost no errors, and some have more than 20 per hour, although the transponder is one.
A few days later, the bandwith is displayed again for 90, it is necessary to restart tvheadend and it is displayed only for 1 channel as everything. Also, when the speed of the entire transponder is displayed, exactly 30 transport errors appear approximately every 15 minutes (they are not displayed in the error counter on the record, only in status > stream).
Maybe someone faced with similar?
