videos in the zip archive from lesson 2 are not playable in windows media player.
I am using windows media playeron win 7 machine(provided by corporate, codec's install not possible).
I am unable to play videos starting from lesson 2 available on the zip file.
But the same videos are playable on the internet.
Please look into this issue. Not a big concern to most of the audience but a very few people like me using corporate machines would find it hard.
