problem with movie texture after build osx and win

I am working on a very big project and now I run into a big problem with movie textures. I have a very simple scene containing only a canvas and a raw image where a ogg movie file is attached to the texture (for testing movie textures). Via script I can start the movie in the editor. After successfully building the game for OSX/WIN it crashes immediately after starting. I have unity pro and no idea how to fix this. Any suggestions? Thanks.

Hi, I have the same problem here. Have you found any solutions?
