While I whole-heartedly agree with you, that doesn't solve the problem. Irregardless of any of the crappy problems with ME, I know the OS can use a CD-ROM. I've also seen this issue happen in multiple other OS platforms, so it is not specific to ME.
Most notably, I've seen this problem occur when the burning app screws up the buffer cache with the CD-ROM, basically confusing the system.
Usually a reboot sorts this out.
I encountered this problem a lot on older versions of Nero, and also when trying to copy ISOs that fill nearly the whole CD/DVD, pushing the index.
If a reboot doesn't solve the problem, trying burning something different. If the burner works for other things, and just not for this, examine what you're trying to burn and see if you can accomplish the burn in another way (or on another system).
