Tvheadend

Hello

I am running TvHeadend 3.9.2357 on a Synology DS211 in Germany via MNET DVB-C and acessing TvHeadend via browser (for sheduling recordings) and XBMC/Kodi (for watching TV). All works perfect except the EPG. Even the big channels don't show EPG very often. Sometimes they do, sometimes they don't. I played around with the configuration in TVheadend for the EPG but with no access. This is how it looks like now.

Any ideas how i could improve this?

Thanks!

!!
