I have two optical drives. One (CD-RW drive) is the master drive on the secondary IDE channel. The other (DVD-RW drive) is the slave drive on the secondary IDE channel. Mythdora is installed on the hard drive (master) on the primary IDE channel.

Here's the problem I'm having:
Say I have the MythDora DVD in my DVD-RW drive. I boot the computer and MythDora boots off the hard drive. I exit MythTV to get to the desktop. There is an icon for the DVD on the desktop. I can browse the DVD fine. I insert a CD into my CD-RW drive. Another icon appears on the desktop. I can browse the CD fine. However, now when I go to browse the DVD, it browses the CD instead. I try to unmount/eject the DVD (by right-clicking on desktop icon) and I get some error like "/media/cdrom is mounted twice". I am also unable to unmount/eject the CD, but this gives a different error (I don't have access to the box right now and can't recall at the moment.)

Any ideas what could be wrong?
