Ok, I found a fix for the tooltips not displaying since what's above didn't work for me...
You need to do 2 things (I'm using the anarchyswf one as an example but you'd need to do this for the anarchyvideo folder too):
1) Add the following to the top of anarchy_media/plugins/anarchyswf/editor_plugin.js:
tinyMCE.settings['language'] = 'en';
2) Rename anarchy_media/plugins/anarchyswf/langs/en_us.js to en.js.
