My issue is this: I don't want my browser deciding what plugins and/or codecs I am allowed to use. I understand that they want to support free software, and that is laudable. However, if I intentionally install something on my computer that _can_ used, then I expect that to be used. I just tested with Safari and I was able to play an mkv 720p file in a video tag because I installed Perian. That is how it should work.
