I have made a video using the "Blockbuster" trailer template contained in IMovie 11. I have only used the audio of the trailer template provided by IMovie 11.
I posted the video on You Tube. Now a company named Pinoytuner Corp claims that the audio infringes their right. Again, I have ONLY used the audio which came together with the trailer template in IMovie 11.
I'm a little bit confused right now because I strongly believe that Apple has licensed all the audio content that is already contained in IMovie11's templates and themes so that it can be used by the buyer of IMovie11 without infringing any third parties rights.
