title: Movie compatibility on Android & mp4 problems
body: <p>I'm writing an app which plays small cartoon movies in Android.  I chose mp4 as it seemed to work well on phones, and appears to rescale dynamically for different screen resolutions.  Great.</p>
  
  <p>The problem is that when I use Bluestacks the movies turn up corrupt:</p>

  <p>I thought I had a solution to this in that I just needed to resize the movies to 400 or fewer pixels wide using imagemagick, which fixed most of the movies but some stubbornly remain corrupted and I can't work out how to get them working consistently.  I've spent two weeks trying different things.  The movies play fine on my phone.</p>
  
  <p>I'm now looking at "webm" format for the movies, which appear to work in Bluestacks but which doesn't work in Froyo and below.  I could ignore the Bluestacks problem of course, but it seems popular and I use it as a development emulator.</p>
  
  <p>My questions are these:</p>
  
  <p>Does anyone know why Bluestacks can't play mp4 movies properly?  It appears to be a rescaling bug.</p>
  
  <p>If I put mp4 movies in "drawable" and webm movies in "drawable-mdpi" (which Bluestacks picks up) then which movie would a mdpi Froyo phone see?   Would it ignore the webm movie since it can't play it, and play the mp4 movie instead, or would it fall over saying it didn't recognise the type?</p>
