here's the info for ixtreme 1.4http://www.xbox-scene.com/xbox1data/sep/EE...uVErbIGVFWP.php
We recently found out that new games ripped with kreon drives will give back a degree, that in combination with ixtreme jitter, will produce a 360 degree value. This would be a unacceptable range (should only be 0-359). This is a detectable and possibly a criteria for the recent ban waves. Also, this would explain why some users got banned playing the same games that others played, and did not get banned. The point of jitter is to randomly give back proper values. With that in mind, a random jitter value from a kreon drive, with a random jitter from a ixtreme drive will rarely give back a 360 degree value. This new ixtreme will wrap that value to ensure that no 360 degree value can be submitted.
basically the recent banning was a result of a bug between the ixtreme firmware and the kreon firmware. if you have a hitachi 78/79 drive and have to wait for the firmware for that drive, then just check your backups with kreon checker. once you have the new ixtreme 1.4 firmware, it will be a moot point though as the firmware fixes the problem without the need to reburn your backups.
