Editing a DVD's Default Audio Track

[tesco]

I downloaded a fantastic 4 DVD.

It's got the extra audio tracks removed so all there is is the English 5.1 DTS.
The problem is that when you go to watch the movie it's got no sound...what you have to do is go into the language selection on the menu and choose English 5.1 DTS.

I was wondering if anyone knows how to change this to the default selection so you dont have to do it whenever you want to watch?:)

Thanks.
