I have some x-box iso's but cannot get them to work properly.I am using winrar to unrar all the files into one big file.Then im using either Primo or Nero to burn the file but the console does not recognise the disc.I know its not the media or the chip as i have some pre burnt that are fine so where am i going wrong?

burn on cdrw or dvdr. use primo dvd with these options: dao, mode 1. close disc. And if ure using dvdr burn at 1X
