A few kilobytes certainly seems reasonable -- I don't think we can
actually do anything with the video until we've made that
determination, so I'm actually quite sure what's being asked.  Can you
describe a scenario where Firefox would have a reliable MIME type, but
isn't retrieving the first chunk of the video anyway?  Do browsers use
HEAD to check for video compatibility today?
