Hello, I encoded a movie with 2 audio streams. In BS player it works perfectly to switch the languages. But I don't know how to do it with Windows Media Player (Version that comes with XP). I created a .mss file, but when I right click on the movie while playing, I can't select properties or language or anything. I installed the audio pack, so the Morgan stream switcher should be installed (How can I check that)? Do you have any ideas what my mistake is? cu Tempe
