I have googled on this firmware but could only find one reference to it http://dvdxcopy.afterdawn.com/thread_view.cfm/177504 which really does not address your problem. Contacting emachine is useless, I have an emachine laptop and there is no support for any updates. My suggestion is to go to this site forum it is strictly for Lite-on drives and start reading it will give you a lot of info on your drive and various problems, fixes and software available. http://club.cdfreaks.com/forumdisplay.php?f=44
Oh WOW...I started reading...and I have no clue as to *what* I'm reading!! Nothing makes sense to me. But I wanted to thank you for your input, and time.
I know it can be overwhelming, but the more you read it will get easier and you will really be able to understand about your drive. Good luck.
For info on Memorex (utter rubbish media), pls see the tribute to Memorex in the 2nd link in my signature.
