Dw-d18a dosen't see disc

Hi everyone. I just ran into a problem with my Sony DW-D18A drive. Have been using it to back-up several movies with no problems using DVD Shrink but the last attempt was unsuccessful as the dvd burner won’t see the disc in the drive. DVD Shrink shows no disc when using the open file button and gives me an error message. Also, my computer won’t play the movie. None of the other programs don’t reconize that there is a disc in the burner either. Haven’t had any problems like this before.

The original movie plays in my Phillips dvd player with no problem. Is this a firmware problem? Thanks for any help you can give me.
