The VideoLAN Forums

I know there are softwares today who can do it (like Beamer http://beamer-app.com)
and it works great still it coasts some 20$

Is that difficult to achieve?

So how does Beamer http://beamer-app.com do that?

So is there a simple answer, if that is possible?

DTS tracks works fine in videos through spdi/f
5.1 Audio tracks (5.1 albums) output white noise ( ac3 is fine )

suggestions ... !!!
