Is there any way to automatically generate a short text on screen showing the active audio track?
eg: "5.1 AC3 Surround" when track 1 is active and "Stereo" when track 2 is active.
This would be placed (say) in the lower right corner of each screen and would serve to remind the viewer that they haven't changed from the default track 1 (5.1) to track 2 (stereo) if they are running on stereo only hardware.
