Ahh, the burden of tape camcorders is the inevitable tape jamming. From what I know, the tape door has either jammed into position (which MIGHT include whirring from the motors) causing the door to stick or to stay in it's position, or something inside the compartment itself has failed.
So for example, when my camcorder broke (tape door would open fine, but the compartment itself would not pop out so I could not insert or eject tapes) no motors whirred or made any other noise other than a bleep to indicate that the door was open, which must have indicated something has failed inside there because not even the motor heads spun. Nothing.
No errors came up, however, just a message flashing "NO TAPE!".
I cant advise what to do, because if your camcorder is unable to eject functionally (Some camcorders are clever enough that sometimes if the unit fails to turn on then it routes power to the tape compartment.
Sorry I'm rambling. Bluntly, if there is a tape stuck inside it, crack out that screwdriver, and prise the unit apart, or, if you can get into it direct, prise the compartment very carefully and remove the tape if its not stuck in the heads. if it is... Consider is it worthwhile to have this tape? Seek expert help if you cant prise it out.
Once you have mutilated your camcorder with a screwdriver (hammer is recommended, but not essential) chuck it and buy a new one. If you get the same format, you have the convience of porting all your filmed archive onto a new camera
