Looking for an explanation

I had a Oporite DD0203 drive and upgraded to a Lite-On SOHW-1633S (F/W SOHW-1653S). None of the data (Files) disc I burnt with my Oporite doesn’t read on the Lite On. However the all the backup movie DVD work fine in the Lite On. I burnt them with the latest version of Nero.

Recopy the data using ISO format. Try finalizing the DVD option.
