Just got a JVC GZ-HD7U camera, and am trying to figure out what the TOD file extensions actually are. The camera comes with proprietary software, which can downloaded the files via USB or fire wire to a computer hard drive, and does basic editing. As the camera is detected in "My Computer" as a hard drive, I found that I could copy and paste them into a folder on my computer hard drive. Vegas does not recognize the TOD files as a video file, but if you have Vegas look at all files, it sees the TOD files, which can be import to the timeline, where they seem to be handled as HDV files. The files appear to be .mt2 stream.
