This is a bit of a long shot, but I figured I'd ask in case anyone has any tips and tricks: I have some AVI files with dual audio tracks (main audio track + director's commentary). The GP2X movie player plays the first audio track and ignores the second - is there any way I can get it to access the second track? (with full-blown MPlayer on a Unix host I'm able use something like "mplayer -aid 2" to get it to play the second track).
