I wasn't trying to rain on your parade or anything, I only just learned about the extended cuts (and I still can't find out if the first film's EE will be released in Canada as Philosopher's Stone or not, as I'm waiting for that to dive into Blu-Ray HP) on DVD and thought of this thread.
I myself would be quite interested in an XviD of this - I think some of the deleted scenes could really add to the film (though I've never actually seen any EE of any HP film).
