Sure am late to get to this, but maybe someone else will be warned. Our organization bought one and then I did personally for my private production work. Neither one operates. The organization trashed theirs. I kept mine with the hope that some day I'll get an answer.
The company's unit worked for a week or so and then stopped. Mine: the DVD drive never accepts ANYTHING I put in it, audio, video, recorded or blank. The HD has recorded a few times, but can't be depended upon. The MiniDV deck is the only thing that I can use. It allows me to capture to FCP on IMac just fine.
The book is poorly written. The book was a budget job by JVC. My GY-DV500 had a pretty good book, but this is too bare. The icons on the screen are too few pixels and not clear. If I had it to do over, I wouldn't. I've had about 5 JVC items over the years, consumer and pro, but this is a rip.
