Came back to this thread, happened to run a page search and can't believe the words CreateSpace were not mentioned Anywhere in this page. Heck, I'm posting this just for Google indexer's sake...
For history's sake, CreateSpace used to be the only option to self-publish videos on Amazon before AVD, and was pretty bad (SD only, for example). It still appears high on relevant search results, but it looks like now if you go on CreateSpace and want to publish your film, it at least directs you to AVD.
