Thanks for taking the time to report this bug and helping to make Ubuntu better. The Ubuntu Live CD is designed to be a "live filesystem" and does not appear as a CD when you have booted from it; this is normal. Once you have installed Ubuntu and are booted from the hard drive, you will be able to use your CD drive normally again.
