Ok if you know anything about downloading movies, I will put it simple for you basically you can burn around 6 movies to a data dvd without converting them to dvd format & pop it in your ps3 and you can watch all them movies instead of 1 on a dvd you now have 6.
PS3 plays divx don't worry about that code you already have divx built in.
Anymore questions email me I will be glad to help any PS3 owner.
Divx is a company that makes their own, unique video format...before DVD burners, the best quality video you could get on a computer was Divx. I own a PS3 too and don't even worry about Divx, stick to Blu Ray...it's way better!
