Had my xbox chipped got a backup game off a friend put it in drive and ok. So, I downloaded slayers.iso burnt it using nero and magic but xbox does not recognise the cd-r, cd-rw or dvd-rw media that I have used. my xbox also won't recognise any other disc that I burn myself (dvd, music or game). What am I doing wrong? Please help. (I have searched the forums but I can't find a similar problem/solution). I don't know which chip I have or which model xbox. All I can say is that I have an xbox crystal which powers up as normal when switched on with eject button and powers up in evox mode when powered up with power button. It has the original hard drive and xbox dashboard.
