Problem with Disney Video Lecture 1

First of all, hi to everyone (my first post). :laughing:
I don’t know if I should download first Disney Video Lecture again because after 20mins I don’t have sound in video.
Anyone had problems with this?

Yeah I also had trouble after the first little bit. The audio just cuts out. Rather bothersome. Second one seemed to work fine. I thought it was just a corrupted download, and was going to try again at some other time. But maybe not?
