DVD-ROM drive only reads CDROMs after upgrade to 10.0
 

I recently upgraded from 9.2 to 10. community
The Benq DVD-ROM drive only works now with CDROMs.
If I put in a DVD and try to get the contents I get a message:
'Mount: Wrong Medium Type'
'Please check that the disk is entered correctly'

Reading CDROMss is fine. I am sure the problem relates to the famous FSTAB file.
If I go to K3b & right mouse click on the DVD-ROM icon and select 'Disk Info', K3b shows the title of the DVD disk and how full it is.

I have tried enabling and disabling supermount and the 'no auto' options in the Mdk Control Centre. Whatever I do doesn't cure the problem.

I have searched google and other Linux website forums for clues on FSTAB without much success. I mean there are plenty of hits, but none describe my symptoms. :-(

Here's the snippet from my FSTAB file:

umask=0,user,iocharset=iso8859-15,codepage=850,no /dev/hdc /mnt/cdrom auto auto,ro,exec 0 0
/dev/hdd /mnt/cdrom2 auto user,iocharset=iso8859-1,unhide,ro 0 0

/dev/hdc is my CDR/W drive (which works fine)
/dev/hdd is the DVD-ROM drive

Any suggestions gratefully received.
