This has been happening the last two or so weeks, never had this problem before. The audio starts to desync, and just gets worse and worse. Refreshing the page and starting the video where you left off works, but then it desyncs again after 15-20 minutes and on and on. Mainly in the HTML5 player, but that's the only player that works for me. Isn't happening in Internet Explorer (haven't tried Firefox), so I assume it might be a issue with the latest version of Chrome or something?
