Mpeg2 Audio


I have the Mpeg2 decoder and QT7 pro but I'm not able to trans-code the Muxed Mpeg2 files to another format that plays the audio. I guess it's because there is no separate audio file? It sounds like Mpeg StreamClip might be the answer but when I try to download it, I get the message that I am not authorized to do this on the server. Help! Thanks.
