whats DVD9 ??
 

this might sound stupid but i always read about dvd9 and i wonder what that is heheh.

I'm pretty sure its how the original makers press the DVDs. If you put a new movie into your DVD drive it will probably show up as over 4.7 gigs. I think they can fit about 9 gigs on one side of a DVD.

guys, its a dual layer dvd, simple as that. 1 layer = 4.7gb storage
