Maybe I'm missing something, but after installing the QT plugin from JVC, I've connected the HD7U via USB2.0, pressed the button and selected 'backup' (threby causing the HD to appear in the finder), opened the camera HD from the Finder, select the TOD files, and dragged them directly to the Clips frame of iMovie6 HD. Takes some time for the transfer, but so does playback via Firewire and a miniDV, and at lower resolution!
Pulling out the TOD files from the other files on the HD is usually easy as the other files are much smaller, so doing a sort by size usually brings out the TODs all together. Once selected, I go back to the name sort (hoping to transfer them by chronological order) and drag over the bunch. However, whatever you do, DON'T create a folder on the camera to hold the TODs...the camera REALLY doesn't like this and it gave me a 'had to run a file diagnostic program to fix your screw-up' message.
Problem I have with this is that as iMovie has some magical way of loading in the files (certainly not chronological) and the JVC labels file name sequencing in hexidecimal, I end up spending a fair amount of time sorting through the files to get them back in the original order. Am getting my HEX thinking back, though...
My only complaints with the camera is this HEX file naming and the relatively ineffective optical 'stabilization', but I don't know how much visible shake is a side-effect of the higher resolution. This is my SECOND camera, as the first had a very visible cluster of dead pixels, and it also seemed to have a lack of resolution that I couldn't explain. The new one is MUCH better. For optical image stabilization, my 'old' Canon Optura 50 is by far the best camera I've ever had, but it's flakiness with turning itself off at times during taping (never could get that fixed) and lower resolution has me now using only at work and my all-important videography with the kids' sports is the full-time job of the JVC 🙂
