So, I figure out what the problem was:
The Blurayplayer works fine with event ghost but not myFilms.
That was because myFilms had a crash and changes the path to the external player.
The exe called "uMCEplayer.exe" for example, but myFilms lost the u and tries "MCEplayer.exe".
I don't know why, but Arcsoft starts with that wrong config, but there are no events for event ghost.
Correct this and it works.
To fix the remote
You must disable the always on top function for mediaportal (even Arcsoft already runs in front).
So thanks for your help!
