If you have some problems reading videos :

Windows users :

> I really advice you to use the windows media player classic. You can download it here

> You can also try that other super player : VLC, another free player. You can download it here

> If you can't read the videos with those players, maybe you need some video codecs. There is a free pack that you can download here. (I use it and i read every videos.)

MAC users :

> I know you can also use VLC player : you can download it here.

> You can download the Divx Codec for MAC. Download it here. (thanks to Tim for the Info).

> If any MAC user have more advices, please mail me, I will put them here.
