Thanks for the info, I will give it a try later. The drive is working fine with MS0M, but I wanted to upgrade to MS0N. I don't quite understand why it doesn't work with MS0N. But I am new to Liteon drives, but with Benq's once you crossflash a drive you can then use all newer versions of firmware with no issues.
I made a quick test disk with Nero on DVD-RAM and it seems to burn RAM fine! Looks like I may have got a good drive and not one that failed DVD-RAM testing
