Go to ANimefreak.tv and click anime list.
Scroll down till you see Code Geass and click it
Click on the episode you wish to watch.
Now when the episode comes up you will have to click on the yellow tab on the video that says english dubbed.
Then click the american flag and click play and there you go. biggrin
This is how i rewatch it so i know it works.

Enjoy
