While trying to play movies from servers some URL's doesn't work. Why?

Question

I am trying to run a streaming video in MPMoviePlayerController. When I was trying some urls like http://code.agilephil.com/fox.m4v it was working. But when I try some other urls like one in our remote server, it doesnt work and in Console it says Playback stopped.

Could anyone help me please?

Answer 1

Something I figured out was 1.it was working when posted in a IIS server even in the simulator. 2. When posted in webserver, wasnt working in simulator but successfully worked in device.
