OK another issue I encountered today. I have a movie with four tracks, one which is 5.1 english and 3 which are stereo which I want to upmix to 5.1. The current application does not allow me to do that,

I must go to DTS7.1, small bug easy to fix, I think in all cases you need to let the user be able to select whatever audio he wants to use regardless of the starting point….
