Ok, I've found the issue and it is my fault
We have in the german XBMC config a command which is named "Activate Window & Browse" and this command contain a payload "XBMCactivateWindowDE-EN.xml". I have insert a wrong value (I don't know why?), so sorry for that.
Please open this payload in the command tree with a double click and press the "Open/Edit" button. Then search the line with the phrases "Filme, movies" (see pic.) and overwrite the the value "videolibrary,movietitles" with "video" and save the payload. This command open only the movie section in XBMC and not all your movie titles by coverflow or similar.
It is not possible to call the movie titles entry direct with this command, use insteed of them the command "Durchsuche Filme" and add another phrase like "zeige Filme".
I hope this make it clear.
There are also some other missing entries in this payload like weather, ... I will correct that later, maybe someone do the job for me
here is the source of information which is needed:
