Tagsistant already supports automatic tagging from the metadata such as you have described. The linked article says it supports plugins that can “extract tags from file contents” in the second-to-last paragraph. So if you want to tag your movies the way you said, you just have to write a plugin that uses some library to extract that data, or wait for someone else to release a plugin like that.

Yeah, I didn't notice that on first read, but that definitely helps seal the deal for me. I'll probably set it up on my server tonight and at least look into hacking together that plugin.
