I've made a DVD of a wedding for my client. The Disc has two audio streams. Number one is the main track; number two is the commentary track. After I burn it, I play in my test DVD player, everything seems fine, but when I play it in the main DVD player in my living room, the default was the Commentary track. Why is it not the Main track that is the default?
I checked everything, I even set the initial stream selection in the project property to be the first audio track.
This is really confusing. I have not notice this before. If anyone have this same problem and know how to get around it, please let me know so I can be comforted.

Thanks for you help
