Ok i have a MacBook and i try to click on a video and it says you don't have the proper plugin. It says you need video/x-ms-asf-plugin something MIME. Does somebody have a QUICK and easy to understand solution without long explanations. Thank you

You need to download Flip4Mac. The free trial version is adequate; as you only require decoding support.

I would actually download VLC - it's an open source video player that will play ALL formats. Flip4Mac sucks imho....

That would work too, although for it to solve the problem, the original poster would have to download the web browser plugin from the following page:

Buy a pc? ;)

Is there a similar thing to ffmpeg for OSX? or a codec pack like K-lite is for windows?

ffmpeg can run on OS X.
