while playing certain .avi movie files.

i can only hear the back ground music, but not the speech.

in other words, i can hear what they talking.

when i use VLC player, i change audio device to 2front2rear or stereo or mono, then im to hear both. (no problem at all)

may i know is there a way to play the file using media player classic. coz i prefer to use media player classic.
