I have pretty strange and annoying problem with DivX I made.
I put 2 audio streams (original sound as first and director's commentary track as second audio stream) but on one PC, default stream is first (correct) but on another PC, itp play second audio as default ?!?!

It is clearyl visible in properties in Windows Media Player that, on one PC, first audio stream is right one and on another it is vice versa (second stream is first) !?!?!

What the hell is that and how to have correct stream order on any configuration ?
