I have some avi files that contained 2 languages ,the packer mix them together,left sound track is one and right sound track is the other..... most players can not split them so I heard two languages when I played these movies..... :(
What I found the only player can split stereo sound track is STHVCD Player:
download shareware version

STHVCD can split stereo sound track,and just play one of them , it also simulated the mono sound track as stereo.....
I really like bsplayer, and I hope this function can be achieved in the future.
Thanks!
