thanks for the fix fused, worked a treat!
ths is what i did:
i had Top Spin NTSC on a dvdr which gave disk dirty message at career mode, so i created an ISO from the dvdr to my pc hard drive using dvd decrypter in read mode (yes i know, but i find this to work great!!), then i used craxtion3.1 to extract the ISO, from there i changed the DIR name to PlayerCreatorMenuPart, then i re-created the ISO using craxtion3.1 , then burnt to dvdrw at 1x using nero.
now career works fine and i used a low quality dvdrw that has been used loads of times b4.
hardware: PAL xbox, with enigmah final.
hope this helps you guys
