I would have thought for music and sport DVDs it makes more sense to use the "role" to state what they played, as opposed to who they played.
For example, I have a David Bowie concert that is credited (not by me) thus:

David Bowie....Vocals
Gerry Leonard......Guitar and Vocals
Sterling Campbell.......Drums and Vocals

etc.

This makes more sense to me than using "himself" or "herself".

Exactly.  I have even heard interviewers say things like "what is your role in the band?"  His role is "Lead Guitarist" or "Drummer" or whatever.
