There was a quick Dothraki lesson the latest episode of Thronecast.

They do a classic mistake people do with conlangs which is to simply look at the dictionary and string words together without any regard for grammar. They use nouns as if they were verbs, use verbs without conjugating etc.
Still nice to get some exposure and hopefully people get interested in finding out more.
