For example, I go to http://jwplayer.com and when I click to watch the video i get the following error: "Error Loading Media: File Could Not Be Played"

Now, for the other error... I go to a website where the video looks like its going to start and then it turns all white with the error "html5: video not properly encoded"

I went to http://detectmybrowser.com and in the HTML5 Video Check section webm and h264 are red (meaning that I don't have those plugins I guess)

So.... how do I fix this?
