Game: Halo 4 Disc 1 -Verified using abgx360 (but not patched using it but passes stealth patches and other tests besides obviously the online database check) DVD Burner: IHAS124B with LiteON MAX Burner firmware. Blank Media: Verbatim MK0030 - Made in Singapore -Burnt using IMGBURN latest vers. Xbox 360 drive: Hitachi 47 flashed with LT+ 2.0 -I know this drive works as I have tried other games using it and it works fine but not burnt games. Dashboard version: 2.0.15574.0 Disc 1: i1284.photobucket.com/albums/a562/photoslolzorz/disk2.png (Image from Kprobe) Settings: 2.4x, OPC off, Layer break - Calculate Optimal Disc 2: i1284.photobucket.com/albums/a562/photoslolzorz/disk1.png (Image from Kprobe) Settings: 4.5x, OPC on, Layer break - Calculate Optimal Disc 3: i1284.photobucket.com/albums/a562/photoslolzorz/DISK3_zps575f79ae.png Best result, still doesn't work. I'm assuming because my drive is an older Hitachi and isn't capable of the ap25 checks that I don't need to patch the iso down to lt+ 2.0?. Both of these discs come up as "Unrecognized disk" on the Xbox 360, what am I doing wrong?, Thanks.
