I was wondering if there was a method or plugin or something that would allow me to upload a movie i made in Movie Edit Pro 15 Plus directly to a video hosting site besides Youtube, like Viddler, blip.tv, Veoh, LiveVideo, Dailymotion, etc. in the MEP program.
All of these services would require a special implementation in the software to interface them directly. This only exists for YouTube and Magix' own online presentation platform (Online Album) in Movie Edit Pro 15 at the moment. You can find the options in the "File" menu under the "Internet" sub menu. If you want to go to any other platform, you'd need to invest a few more mouse clicks and render a suitable video file via "Export movie" in the "File" menu first, which you could then upload through the appropriate function on the respective website. Ultimately, you will get your video on any of these video-hosting sites, if that is what you were wondering.
