I've had nothing but problems with my LG dvd drive. When I first got it I had no problems with it. Later on though it all of a sudden failed to read DVD's, but would still read and type of cd. CD data audio etc. I sent it away on it's manufacture's warranty. When it returned I hooked it up and it ran fine. But the next time I went to use it, one boot later it wouldn't recognize dvd's again. I had already tried many options when it first happened and went through all the settings, drivers etc on and on and came up with nothing. So I tried something different and switched my dvd to master and my cd burner to slave and it worked, but only once again. Next time I went to use it on the same boot it failed to recognize the DVD again. Any input would be much appreciated.
