So glad you enjoyed the DVD, Dave. From what I've seen of what Rupert's done with the book, you won't be disappointed there either.
As for the USA, I've just signed a distribution deal with the Disinformation Company of New York and the DVD will be available over there from about May/June next year. I never did have a run of NTSC copies manufactured 'cos the PAL run was all I could afford. However, I do have the capacity to burn one-off NTSC copies to special order if your friends are really desperate!
Best
Michael
