    so, i have a movie in avi format. when i look at the file properties it shows '2 channel.' when i burn it to a dvd and play it on my dvd player, the dvd audio menu also shows it as 2 channels. however, when i listen to the movie, it is clearly surround sound (5.1). i'm not an expert in digital movies and was wondering if this is correct? why would a movie file show as being 2 channel sound and play as 5.1? thanks.

    Demux the audio and stick it in an audio editor and see how many channels it has.

    Dobly Pro-Logic uses a method of encoding surround sound information into a stereo audio track. It's not uncommon for conversion programs to convert discreet 5.1ch audio to Dolby Pro-Logic, even when converting to MP3. The quality of the surround sound may not be terrific, but it sounds like your AVI audio track uses Dolby Pro-Logic which is then being decoded to surround sound by your player.
