I have an app that\'s worked since version 2.0 of the SDK where I create and add a UIWebView and then load the URL of an .mov to play a movie. Ever since the early version
I got a situation of "this movie could not be played" when playing a video clip. This happened when recorder was just used. And this would NOT happen when player was just used.
Then I set audio session category to kAudioSessionCategory_AmbientSound after recorder finished.
This problem was solved after I did that.
