I got Swap Magic 3.3 for xmas, and I haven't gotten one backup to work since then. I've tried using Nero and DVD Decryptor, but everytime I try to run it using both the CD and DVD version of Magic Swap 3.3, I get "Not a valid PS2 disc" error. I've run a backup of the movie Army of Darkness on my PS2 so I assume it can read all DVD-R's. I've tried burning the backups on Memorex, Sony, and Maxell. I am pretty sure I am using the slide card correctly, but since I haven't gotten one backup to work I'm probably not doing it right. My DVD burner is MAD DOG MD-16XDVD9, incase that info is needed. Do any of you have any idea at all why this isn't working? I've looked numerous times on this site for an answer, read several FAQ's I found, and I haven't found an answer yet to it.
