Telekom Entertain on MythTV

[mic3er]

Hi,

I'm using Mythtv now for several years with DVB-T in Germany and all fine.
Now they will change end of March to DVB-T2 and less free channels.
So I changed to IPTV.
Found a very good guideline to configure "Telekom Entertain on MythTV":
https://www.mythtv.org/wiki/Telekom_Entertain_on_MythTV
Scan for channels is coming up with the message 18 channels found but under channel editor nothing is shown.
Terminal is showing me:
EXTINF:-1.(1) Das Erste
ChanImport: Found 18 channels
The playlist is working with VLC also on my mobile.

Any idea why the channels didn't appear?
Did I miss something?
