Multi audio tracks don't show in QuickTime Player menu

But they show up when playing back with MplayerX.

See attached pics.

First: in QuickTime Player

Second: in MPlayerX

Dunno, I am not a seer. Check if you have the right alternate groups and if the audio formats are supported in QuickTIme.

Thanks, Damiano. What's function of "Alternate Groups". I searched wiki, but couldn't find it.

Could you open up the file in question, and give us a screen shot of the Subler window?

It's likely that one or more of the audio tracks is not supported by Quicktime.

@AkuKnives I figured it out. QuickTime Player can't handle DTS 5.1ch sound tracks. So it doesn't show up in the menu.
