After putting in 400 DVDs I recently have a problem with some DVDs which are not recognized by my LG 4160B.
Explorer simply asks “Please insert the disc into drive E:”.
DVD Shring says “No Disc” although disk plays in my DVD player.
My friend having LG 4163B does not have this problem.
For other DVDs I can hear a noise when I put it in but for a couple of the troubled disks I do not here any sound, just a couple of blinks.
