Thank you!
Now, Webplayer works,
but every few seconds, sound stocks and the video has lot of fragments while epg scan ota is active.
Without active epg scan, everything works fine.

error only occurs on transcoding / webplayer.
watching stream over vlc or kodi while epg scan ota is active, everything works fine.

Check the CPU usage. It appears that your machine is not able to handle both.

CPU Usage about 10%,
TV Headend runs on a DELL Poweredge T20 with an Intel Xeon CPU E3-1225v3 (4x 3.20GHz) and 8GB RAM.

And error only when epg scan is active and epg scan Switches to another mux.

Here's another log:

This is the culprit. The input stream has errors. It might be a driver / USB driver / USB bandwidth / coaxial cable interferences issue.. I cannot exclude a bug in tvh.. You may use --tsdebug option to capture the stream received by the driver before any processing in tvh to check, if there are continuity errors in the received data from the driver.

Hi,

ok, how to use --tsdebug?
completely Linux newbie

if it does not happen when no scanning is going on, it's most unlikely that a tsdebug could help. As you have more than one card scanning in the background, try to limit your setup to two adapters for testing, one for watching, the other for scanning and see what happens (also change order so that streaming adapter is either CXD2843 or STV0367).

Sorry for my bad english... :(
Hope you can understand what I mean.

I've testet a lot.
When setting "forcing epg scan" every channel on every System (kodi, vlc, webplayer, recording) has problems with continous errors and video has fragments (unplayable).
Tuners seemed to be locked for scanning.
Disabling tuners for Initial scan and eit scan, watching tv while scanning is active works (with the free tuner).

With no forcing epg scan, and only inital scan, vlc and kodi have sometimes problem "freeing" a tuner, sometimes works, sometimes not, maybe, it only works when Tuning to an program, which is on an mux which is currently scanned for epg?
and webplay have still Problems, sometimes only Sound, sometimes fragments and sound stock.

Sometimes I Need all of my 4 tuners (Formula 1 on Sky with all Feeds for recording).
Normally I use the Initial epg scan and forcing epg update, to be sure, epg is active, Server don't runs 24/7.

Error occurs first time with Version 3.9.2469, i've made a ticket, but haven't test enough and ticket was closed, because solution with disabling forced epg scan was good enough for me.
https://tvheadend.org/issues/2659#change-12388
With older Versions, I think, November 2014, everything worked. Forced Initial epg scan, and Tuning/recording, frees the current tuner.

Maybe it's a Driver Problem, coaxial cable installation excluded, because it's new, and testet from a technician, living in that house 3 month. completely new Installation.
Using Digital Devices DVB-C Cards. ==> Good Quality Cards and good Support for Linux. And, a year ago, with another TVHeadend Version it worked...

Forgot to say: error with fragments and sound problem while forcing epg scan is only on encrypted channels.
USing OSCAm via DVBApi.

encrypted HD channels.
SD Channels are working.

so, my last post today... sorry for spamming.

currently, setting only one tuner to "Over-the-air EPG" and "Initial Scan".
EPG Grabber uses "Force initial EPG scan at startup"

On Startup, only one tuner is tuned for epg... the other tuners are free.
Tuning to encrypted HD Channels ist working. No fragments, no Errors.

check your BIOS power management settings, try to disable C6/C7, I had one mb/card that only worked with it beeing disabled. And if it still does not help, I would suggest to install an earlier version to check if that still works.
