I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: I bought the ZR45MC camcorder in Sept '02. I have been using it quite regularly. then all of a sudden I cannot load new or old mini DV cassettes. The moment I load a cassette, a message flashes on the screen 'REMOVE TAPE' and beeping sound is generated together with a flashing 'EJECT' message. Next step, I ship this to the Canon Factory service in NJ. They replied with an estimate of $160(on top of the $654 I pad for this!!).Also most importantly when I shipped from the Fedex office in Boston, the Fedex person made a remark that she has been seeing quite a number of the Canon camcorders going to NJ for repairs.To sum, I think this is a racket Canon has devised to rip off customers.So beware when you buy a Canon camcorder, ask the retailer about the tape loading mechanism, and if they have any maintenance plans that will repair it.
Solution:
Negative
