Liteon 812s DVD Burner not working

to start off , it wont seem to recognize a blank cd. when i put in a blank cd nothing seems to detect it has a blank cd. When i try and burn anything with nero it just says -Failed- under recorder state .
I did make a backup of one of my dvd’s , and it reads the movies fine…just wont burn anything. im using Legcay 4x dvd-r disc’s

Just tried to update the firmware to ( US0N ) and it said " unable to flash firmware … please contact your vendor "
Just got it in today from newegg

What are your system details? eg what operating system…etc?

Windows Xp pro
Athlon 1700+ , 1gb ram
