Arena: The Brian Epstein Story (BBC?)

I am distressed that I cannot find any copies of this, but I see it's been rated by people on imdb.com.

Does anybody know how I can obtain a copy of part I and part II of this? I believe it was aired/made by BBC at some point, and has been chopped up for A&E bios, but the original versions just don't seem to be out there. I've had problems obtaining other BBC productions before and it seems odd to me that they would make certain seminal works and then not sell them.

Anybody have any info on how to get my hands on a copy? I'd be eternally grateful.

many thanks.
