I contacted the BBC outlet here in Sydney. The video 'The Wrong Stuff' is still available, but is $249 oz plus $20 p&h (local).
[email protected] is the person you need to send an email to for further details(She is in Sydney). For info, their address is;
BBC Worldwide
Level 11, 50 Berry Street
North Sydney, NSW 2060, AUSTRALIA
I didn't ask about the other video, Jan might be able to help with that one.
