title: Playing .ts files using AVAsset? -> The media format is not supported
body: <p>I'm working on my final university project and deveolping an application for iOS 5 that demostrates how HTTP Live Streaming protocol works.</p>
  
  <p>The application gets a list of diferent HLS sources to play. They can be player using the internal iOS mechanism: passing the m3u8 directly to a MPMoviePlayerViewController, or using my own player that I'm developing that performs the protocol step by step.</p>
  
  <p>The idea is to demostrate how it works, downloading the .ts files and choosing the correct stream depending of the download speed at this moment.</p>
  
  <p>The first option, the easy one, works perfectly. MPMoviePlayerViewController does the work. However, when I use my own player, I download the .ts file, but when I try to use it in a AVAsset it says me that the media format is not supported? How can it happen? if the system is able to work with a .m3u8 file it means that the system is able to play .ts files.</p>
  
  <p>Can ypu help me please? or give a solution?</p>
  
  <p>Thanks.</p>
