Phil. Sorry. The ones I can slow down are the ones I filmed off the screen with my digital camera which I loaded into my pictures. When I recall them I have a bar underneath which I can manipulate as I said before. I don't know how, but with Luca if I do it a few times it goes into slow motion and stays there untill I close it down. The music plays at the normal speed and finishes ages before the slow motion dancers. Its a good way to go. Because streaming uses up your hours. This way doesn't. Good Luck

Phil. I use InterVideo WinDVD Platinum.
