Thanks folks, I never thought of seperate audio files allowing different languages. I've always wondered how it was done.
Tried encoding and everything is great.
I have a quick intro which plays when the disc first goes in. This then goes to the main menu.
Odd though that on my DVD at home it jumps into one of the film about 20 seconds in. It just seems to be my DVD player, everyone elses seems to work fine.
Ah well.
Cheers - Chris
