Has anyone ever heard of a file type called ASF? I want to put a file on a bacground but it won't play on a Mac. It plays on a Pc (and I presume it has sound but the Pc has no sound thingie). Can any one else play it or know of a converter into AVI or the other thing? I tried to post this from the Pc so if it's not working from the Mac I will try it again.
