Cassette removal from dead Canon MV650 Camcorder

I just solved my own problem by disassembling the camcorder until I had access to the little motor which operates the eject mechanism. It sits on the corner of the mechanics subassembly, close to the cassette. By applying about 3.5 Volts DC from a regulated power supply to the two motor contacts, it started to operate (test which direction it needs to go by trying both polarities) and lifted the cassette out of the play position and ejected it. Only since the tape was still wound around the drum, I had to use a thin tool to turn the cassette hub in order to tighten the tape a bit. Then the protective cover of the cassette closed and I could slide the cassette out of the slot by hand. Bingo!
