What do you really mean by "unmountable"?

Do you mean that once they are mounted they cannot be unmounted (ie, 
cannot use 'umount /dev/sdX)? Or do you mean that you cannot MOUNT the 
discs?

And if it is the latter case (cannot mount them), what setting do you 
have in System Settings>Removable Devices? (And if you start Dolphin 
does the DVD disc show up in the left-hand window?)
