what do you mean drivers good?? my dvd drive or software? sorry its not clear for me. can you please explain more for me.
when I bought my dvd drive I just connect it and I let the computer detect it. and I install nero 7 as my player. I dont know why no sound if I play dvd movies but cd and vcd are all ok. is it my computer is too slow or under requirement of this dvd drive(LITEON)?I read from the box, : REQUIREMENTS:FOR DVD R/RW PLAY PERFORMANCE
