My Lite-on 163d DVD-rom has this problem where when I put a dvd or cd or a music disc in it, the dvd drive cannot be browsed. I click on the drive and it please insert a disc. Music cds play when I use Winamp though. But when I restart the pc with the disc in it I can browse the files on the disc. Autorun is disabled on my dvdrom drive and cd burner in windows xp. I have tried a firmware update but still have the problem.
