I have Magix Video Pro X2.5 on Window7 base. I remember in the past making Video Disks with more than one Film but now it does not work somehow. I tried changing the format/codec of the film to MP4, MXV or mvp, I do create a new Button but as soon I go to add second film, the window eccepts only "Bild Datein" and none of the video datei. Even this Window does not show me place where I can add next film to this new Button.      Please help
