DivX decoder problem during iPhone development

I got a strange problem, and unable to play any kind of movies in my iPhone simulator. iPhone just gave a very unhelpful error messages – “The movie could not be played” if I try to play it from internet. Fortunately, if I play the movie locally, I can see some error message from the log :

It might be caused by DivX decoder that I installed recently. After removing DivX Decoder & Encoder component from /Library/QuickTime, now I can play the movie locally.

But there is still another problem when I tried to play from internet – from my local server; it still won’t play the movies ! .. I tried to download it manually with firefox, and it seems like this is the problem with the mime type. After fixing mime types in the server, voila .. finally I am able to see it running in my iPhone
