I have the same thing happen too. The opening plays fine. but when it gets into the episode, parts of the screen go blocky and blurry. Then when it reaches a certain point whatever player I use freezes. I had the most recent version of DivX, so I'm downlaoding that VLC player. If it works, I'll post again.

EDIT: I downloaded the player, and it works perfectly. Also, to my surprise, it also plays OGG files, which I've had a hard time getting to work. Thanks for reccomening VLC!
