My lg super multi dvd rw, is not working properly anymore, when i put an audio cd in it wants to start it in windows media player but it crashes. and when i put a dvd in, i wait like 5 minutes 'til he (the dvd rw) reads it and then he tells me that it's a blank dvd. What should i do?! no money for buying a new dvd rw at the moment, help!!!!
