Ok, so I downloaded some xbox games which unzipped to iso files too big for a standars dvd, and my burner doesn't do dual layer discs. I tried ftp'ing the isos to the xbox, but they don't work. I tried extracting the files from the isos using Qwix, but it just says 'no xbox identifier marker, maybe file is corrupted'. I tried Power Iso, but still no luck. Is there a way to use the isos other than burning them to dual layer discs?
