I think your imac isn't frozen, it's busy to read the dvd. It seems that the laser unit in your dvd drive is burned out. This happens slowly. First it won't read self burned discs and then regular discs won't play too. The only way to fix that is to replace the disc drive or to use an external (usb) one.
To get back a normal boot speed eject the inserted dvd by pressing and holding the mouse button during imac startup.

Thanks for your response, but let me clarify:
The situation I describe with the screen freezing while the pointer still moves occurs without any disc in the disc drive.
Previously, I was able to eject the disc that had been in the drive exactly by the method you suggested.

Hmmm… this behavior is also possible if an connected device, e.g. usb hard disk, don't answer. Try to disconnect your peripherals and connect it one by one to reproduce the symptoms. In worst case it's your internal hard drive that's going to break down, especially if it makes clicking noises.
