LiteOn LDW451S 4X DVD+/-RW Dual Format DVD Writer problems

i recently bought my lite-on dvd writer , worked fine for the first couple of days , but now it wont work at all i’ve tried using dvd decrypter but it just keeps waiting , and using nero it says insert a disk , sometimes when i reset my pc it says something about dvd writer incompatible but other times it is fine , can anyone help me pleez!!!

i have the same problem. sometimes the dvd writer will recognise a dvd but will take a long time to do so. i share your pain. if you find a solution please let me know.
