Tvheadend

Hi guys,

first i have to execuse me for my broken english, i hope i am able to explain what exactly i am searching for.....

In the TVHeadend GUI/Electronic Program Guide and also in the Digital Video Recorder Section we see a row for Episode Informations.
That "Field" for each recording, is in all cases in my configuration empty.
Now i have figured out that each recording has in "/storage/.xbmc/userdata/addon_data/service.multimedia.tvheadend/dvr/log/" his own File with Meta Information.
Now i need to know what i have to fill in such a logfile to make the episodeinformation visible in the GUI.
I will write this additional Informations by hand, each by each first, later i will develop a shell script to compare against a database, but thats secondary. I need only the Information how i can add a Episode Info in a way that this would be displayed in the WebGui.

My Files are showing like this sample, you can see there is no "Field" for a Episodeinfo in there.....
