I have a movie file (“xxxxxxx Ac3 Cd1 Sharereactor.avi”

. The problem is that when I play it in WM-player the audio track it plays isn’t from the original movie but instead it plays directors comments about the movie. I quite a newbie in these movie things but I suppose the file has also the original audio track. Am I right? If so, how can I select the correct audio track? Should I use some other media player?
Regards,
Ramon
