I found this the other day, and it is a pretty good introduction as to why somebody might want to learn Buddhism. It is fairly light on the science (mostly rhetoric), however it more than makes up for that with the generous and sincere enthusiasm that the presenter feels for his subject. He describes the basic concepts and his own motivations with a simple eloqence that is very inspiring.
As a bonus you get footage of a legendary master, Trulshik Rinpoche, as well as interviews with Matthieu Ricard (a monk and author originally from France), and beautiful scenery shot in the Himalayas.
