Error cracking CSS key

[Greg Kilfoyle]

I've not received any replies to this or seen anything on the list. Does
anyone have any ideas? Do I need to provide more information?

This is a DVD that my daughter received for her birthday last year from
overseas and she's not been able to watch it yet :(

Cheers, Greg.
