Sorry to be pedantic, but autobiographies are books written by the person themselves. To have an autobiographical DVD it would at least have to be written/scripted, if not also narrated, by the person it was about. Likewise DVDs about companies can't really be autobiographical. They can be self produced by the company, but would still only be documentaries.
Back on topic, my favourite biographical WWE DVD is still 'Hard Knocks'.
I'm also getting tempted to buy 20-1 when it comes out. Although it's only really a partial bio of Takers career. But I think having all those matches to rewatch would be cool. I just hope they let him and some of the opponents narrate the matches (as an optional commentary)
