I wanted to post the CORRECT DVD cover dimensions...
Because, all over the internet it says 7.125 inches by 10.75 inches.
I believe they are this size in europe from the covers I have downloaded.
For USA, The correct size is 7.19 inches by 10.75 inches.
I have measured them with a ruler, and also confirmed by NTSC cover downloads.
Its not a huge difference, but enough to mess up your dvd cover.
Just printed out some really nice covers for xbox 360 and ps2. It looks really good on photo paper that I got 8 sheets of at the dollar store.
