Tvheadend

Hello everyone!

is anyone using kodi(Isengard) + tvheadend(4.1-980~g2a83381) + iptvsimple(1.11.5).
Watching channels works like a charm using this url: (love tvheadends transcoding feture realy! )
http://192.168.88.150:9981/playlist

i added this url to the epg tab of iptvsimple.
http://192.168.88.150:9981/xmltv/

epg is empty then. what to do?
I can download easily the xml from that url an it looks like this:

Thanks!
