Same problem - sort of
How's it going. I just bought the DVD as well. Unfortunately the whole thing crashes when I try to open any of the lectures. I get a Macromedia Projector error. After trying several fixes I'm finally giving up.
In any case I can't really help you with being unable to see the play, stop, etc. buttons because I haven't actually seen the movies either. However, when I resized the window I was able to adjust the screen size and everything. So you may just have to do that.
The files on the DVD seem to be hidden so you have to use another program to check those out. I really like space monger and also have free commander installed. Once you use one of those programs you can see the contents of your folder.
After doing that I was able to finally watch the videos as well (just in case anyone was interested or also had problems).
I hope this helps!
