tvheadend DVB EIT is not refreshed automatically

Hi guys,

I'm using tvheadend with dvb-c.
Only the DVB EIT is enabled.

When i start tvheadend, the epg is filled, but only once it is never updated again.
When i toggle the "EIT DVB grabber" checkbox (under "OTA Interfaces") and click "save configuration" my epg is refreshed within 1 minute.
So refreshing does not happen automatically.

Any of you guys experience the same?


tvh version:
3.1.622.g3db46.dirty, ziggo
