seems like the only thing provided by `transcripts_presence` is `html5_local` (I'm pretty sure local == our app servers), so I don't see what `html5_server` (the equivalent of the youtube servers) would be.  If that's the case, `html5_server` and `html5_diff` statuses don't really make sense.

(`html5_equals` in the  `transcripts_presence` dict seems to be something else.)
