I follow as usual the ”front end” in video technology and  have installed better software to convert  powerpoint presentations into flashvideo and as a result  slideshows with higher quality – Video now also played in similar player as Youtube

 Tip 1 Clic on symbol Pause a while ( left on the player)  if you need time to read text or if you get get frequent stops ”due to loading” and then start video again-

Tip 2 View in full screen mode  (When High Quality video) -clic on symbol to the right on the player
