Tvheadend

Hi Guys,

I need your help with my setup! I'm running tvheadend "HTS Tvheadend 3.9.2752~gcb98d6a~trusty" on Ubuntu x86 I've got 5 clients all running Kodi Helix 14.2 2x Mac 1x Raspberry PI 1x Raspberry PI2 and an Acer Revo my problem is that on all except the Mac's the audio is cutting out after a while but only on HD channels I can't figure out why I've tried different distros on my Acer and all RPI's are running latest openelec I've also enabled the logging in TVheadend and the log entry just after the sound cuts is for example :

Loglevel debug: enabled
2015-05-06 20:22:36.532 TS: London/545.833MHz/BBC THREE HD Transport error indicator (total 1)
2015-05-06 20:22:36.532 TS: London/545.833MHz/BBC THREE HD: H264 #7001 Continuity counter error (total 1)
2015-05-06 20:22:36.532 TS: London/545.833MHz/BBC THREE HD: AAC #7002 Corrupted PES header (errors 1)
2015-05-06 20:22:36.532 TS: London/545.833MHz/BBC THREE HD: AAC @ #7002 Continuity counter error (total 1)

My tuner is a Silicon Labs Si2168 DVBT used in the UK

All "faulty" devices are connected via cable but restricted to 100MB Ethernet could try to connect it to a 1GB port though

Also tried different settings in Kodi but I don't think it's a problem in kodi.

Any help appreciated if you need more info let me know.

Thank you very much in advance
