Cannot insert tape into canon MV800. Always ejects

Question

I recently charged my camcorder and message cam up on screen to remove tape. i ejected tape and reinserted it but it spins up , bleaps a few times and auto ejects. The tape does not retract into the camcorder. If I remove the tape, (I have tried several tapes) mechanism retracts normally when empty. however as so as i put tape in again, same old problem it will not retract and auto ejects. Is this a major repair or is there a simple fix?
