title: HTML5 Player is slow on some Devices?
body: <p>I've recently switched my clients site from an FLV video site to an HTML5 MP4 site.</p>
  
  <p>In doing this they had a limited size server so we couldn't do flash fallbacks...</p>
  
  <p>Yet we have the site running well on iOS devices and most laptops but he tells me sometimes that the videos take verrrry long to load on their Macbook... I assume they're on Safari which I am myself using and it works fine.</p>
  
  <p>But what could cause differences in playback start times? I know internet speed does but they tell me they done it on an ipad then straight after did it on a macbook and the macbook failed to load the buffering video in an acceptable time.</p>
  
  <ul>
  <li>Could it be:</li>
  <li>Browser versions?</li>
  <li>Server Configuration?</li>
  <li>Operating System?</li>
  </ul>
  
  <p>Im stumped! But either way, they all work sweet on my iMac, iPhone, Macbook Pro.</p>
