This documentary is a pretty interesting look at how digital technology and participatory culture collides with Hollywood/RIAA, etc. It's called Good Copy, Bad Copy and while I can't really think of a link to comics, if you're interested in copyright and Web 2.0ish creativity I think you'll find this pretty insightful.

UPDATE: While I'm in a copyright sort of mood I'd also recommend this clip created by Professor Eric Faden of Bucknell University - it's called A Fair(y) Use Tale and it explains copyright and the fair use exception and is constructred entirely out of clips from Disney movies.
