hello, it seems lately that i have been having a problem burning a movie onto a dvd for backup. the problem is that whenever i run any burning software such as nero and intervideo they always fail to burn and my disc remains blank. I updated the firmware, reinstalled everything, ran all the anti-virus and such. It used to work just fine but now it doesn't and i cant run system restore because theres no point to get back to. Does anyone know how i can get my burner to start burning?
