Movie releases have multiple audio tracks

So a viewer recently had an issue where he was playing a movie we subbed, but got the audio commentary track instead of the normal audio track.

This is a first for me, but apparently the commentary track was the default track in this player. But the viewer was luckily able to find the audio setting which let him switch it to the other audio track.

This is useful knowledge for people who have surround sound systems. I usually encode it so that the audio track is Stereo by default, but most movie releases also come with a Surround sound setting, in case you want to take advantage of that.
