GAME: NFS U2 MY XBOX: matrix mod chip + evox D.6ef bios + evolutionX dashboard v1.8.3285 BACKUP SW: Flash FTP v2.1, xCraxtion v3.1, DVD Decryptor 18.104.22.168 PROBLEM: Original of game runs fine. However, backup copy has very slow frame rate (eg: 1fps). Tried DVD-R and DVD-RW media, with similar, but not exactly the same symptoms. In one case, hangs on loading of game. All menus are OK. RECENT UPGRADES: New DVD Drive. However, previous DVD drive had the *same* problems. New drive does work better, as a previously unreadable original now works fine. END.
