I have a question about an error message i am receiving when trying to download pics and video. Can you help? i get this message every time i try to download pics or video: device drawing to much power

That is relating to a the Harddrive that is in the camcorder. I ran into that error a few weeks ago during a repair. The unit seemed to operate ok but that error would pop up from time to time. I replaced the harddrive and the unit has been working fine. If its still under warranty, send the unit to JVC.
I hope this helps.

No disc for my JVC Everio GZ-HD7U

You don't need the disc. Buy Corel's latest videostudio x2 for editing. To extract the video files from camera just plug into computer with USB cable and search the camera for files.

Download cd's for jvc gz-mc100

this camera doesn't come with software to transfer videos. Just plug your camera (or insert the cf card, on a card reader) and copy your videos to your pc. you can use the image import feature on windows to do the job (but don't delete the videos with your pc. If you do the camera will state a error)

hope it helps

HHD Error

I fixed my hdd error by connecting it to my PC while in camera mode (which still worked) versus video mode and that allowed me to browse both still and video images. Afterwards the camera hdd error cleared and I did not lose any files.

I think this was originally caused by removing the camera from my pc while folder was still open. In the future, I will stop the device using my pc before remove cable.

The video is .mod which is not the most common of files.

Here is the JVC site for this model, you may find some of what you need there.

Also, I use a program called Adobe Premiere which can convert the video files without any trouble at all.

You may want to install the software that came with the camera, there is a video editor and can help you with the files.

Good Luck!
