Please excused my bad English, I come from Austria!
My question would be, I can with this plugin also a "Ant Movie Database" read? If not, perhaps later times the case that this works?
No you can not using an external database (Ant or anything else) with Moving Pictures. This falls under the domain of MyFilms. I think it is unlikely we will add support for this in the future, mainly because this is what makes MyFilms unique, but also because we want to focus on usability. I think using an external database siginifgantly increases the complexity of the plug-in, plus using an external database would by-pass the majority of our functionality.
We will eventually be adding multi-seat support, if that is what you are getting at, but that will not be for a while.
