DVD Help

You know when you buy DVD's some of them have extra features that are only accessable via computer well I have just got a new computer and I tried accessing these features on my computer and it won't work. Anyone know why that is and perhaps how to fix the problem?

What application were you trying to open them with?

I use Nero to burn and watch films and all special features are accessible.

Also VLC Media player works a treat.

I'm using interactual player.
