However, since you have all those extras on Life of Brian, why don't you make a DVD out of them, put that "Pythons" BBC special in there too, and thus create a second disk for LoB. Then you can take the UK version of the film, and insert just the two commentaries.
And there you would have it. A 2-disk fan made DVD version of Monty Python's "Life of Brian".
What does everyone think?
PS: Do you have any extras on Idle's Splitting Heirs, by any chance?
