I havent. I dont even have greasemonkey in my addons page even though the app manager is telling me that the plugin is there. I have the mediaplayer pluin but that only works for some dvix videos that wont play in the browser. I wish I could get a choice for any and all videos to either play on the browser or on media player. A plugin like that would be great as it would make any depency on a flash upgrade kinda irrelavant.
