I too have a problem with this DVD drive Lite On DH-20A4P for the last couple of days. After burning DVD's and putting them back in to check the data, the files are missing. It shows as a CD-Drive in My Computer. But actually the data has been successfully burnt. But somehow i'm not able to view the files burnt or play them.
P.S.: I used Nero v7 to burn the files at 16x speed. I also tried at the slowest possible speed as well at 6x. But both to no avail.
Please Help.
