I don't know if it can actually show more than one device under cdrom, I only have one installed, so I couldn't tell you for sure..
However, manually controlling the mountpoints for the appropriate device name should allow you to mount more than one cd/dvd device..
--there are a few commands that can help determine the device name, mount is one..
/dev/sr0 on /media/cdrom0 type udf (ro,nosuid,nodev,utf8,user=mintuserID)
Mine's exists because of /etc/fstab
So, if you can determine the device name for the two dvd drives, and if there are on the same ribbon cable, then it will be the next letter or number , like /dev/sr0, next is /dev/sr1, or /dev/sdc, next is /dev/sddYou could then just duplicate the entry for the one that is in /etc/fstab (media/cdrom mount ), and change the last character (# or letter)
Let me try and be clearerdetermine the device name for each optical drive that is installed in your computer
The easiest way to do that, insert a disk (media) into each drive and check
In a terminal
type the command dmesg
--look for the device name appearing when you inserted removed the media into each dvd drive..blkid was just to find the uuid identifier
--you don't have to use that, you can also use the device name , such as /dev/sdc
And yes, you would have to mount it somewhere to see if you can have both drives mounted, hence the two different directory names
--pick you own names, and your own directories (folders); as long as you can create a directory with mkdir, then you have access to that location, and can mount the device sudo mount /dev/sdc /tmp/mydvd/dvd1
..that's the idea
And about as much as I can explain it..
