As far as I can see, it hasn't been officially released. Your only chance at this point is for someone to have recorded the broadcast. I didn't, I'm afraid (nor did I watch it, for that matter).
As Covjr said its not released as of yet but I need to speak to our dvd supplier at work in the next couple of days so I could ask for you if you want?
If its soon I can happily send it your way.
I'd forgotten it was out actually. My partner is a huge Pratchett fan so I will be buying a copy for us as well!

Thanks - that'd be great! I didn't know if anyone managed to tape the show. Just watched Hogfather (after finishing the book). They did a pretty good job with it.
