Tvheadend

The problem h264 streams are taken from DVB-T and multicasted to network by vlc. Possible cause is that DVB-T provider is using somehow exotic transcoders, maybe that is the cause of all this.
I can watch H264 channel by udp://@ on vlc with no problems. I am appending log from tvheadend.

Service details of transport in tvheadend ui show h264 video stream
pid, and sometimes log shows lines like:

Mar 13 19:20:21 TS: 0.0.0.0/: H264 #70: Continuity counter error, 1 duplicate log lines suppressed
Mar 13 19:20:21 TS: 0.0.0.0/: MPEG2AUDIO #68: Continuity counter error
Mar 13 19:20:21 TS: 0.0.0.0/: MPEG2AUDIO @ #69: Continuity counter error

Maybe packets are lost on remuxing...
