I can't write my xbox dvd 9 image on a dual layer verbatin on my flashed Nec 6450a to a 6500a v 2.44 on my laptop.
The drive is flashed perfectly it writes dvd-/+r with no proglems.
When I tried to write a dvd 9 5,09 gb image then Nero 22.214.171.124 said Invalid disc error.
The iso file is ok I testeded it on my xbox hardive it worked.
I used this files NECWinFlash.exe 223_14.10.04.bin.
