Awesome! Totally awesome.
If possible could you post a picture of your camera and mounting apparatus? I've been trying to take a video of my favorite roads for quite some time, and everytime the camera has way to much shake going on. I have looked into the new Sport "lipstick" cameras that mount to your helmet. The problem with that set up is to date they haven't come out with one that would hold anymore than a few minutes of film storage.
You have obviously figured this one out as you really nailed it! What a ride! 
Thanks do much.

Grizzly...I attach the camera (Sony DCR-HC48...already outdated, but it's a fine little camera), to a quick release mount/plate made by these folks
http://mountinginnovations.com/QREMM-SL/QREMM-SL-Pics.htmIt's basically a RAM ball (1" rubber) mounted to a quick release holder/plate. That makes it very easy to take off and remove the camera, still allowing it to fit into the small bag I carry on the bike, as the only thing that resides on the camera itself is the plate, and not the holder. It is VERY secure...I have used these types of mounts for many years in the field with still shot cameras of all sizes/shapes. Quick releases are the only way to fly, IMO. The handlebar mount is just the typical RAM U-bolt clamp (I have 1 1/4" bars, but it's available in almost any size) with the 1" rubber ball. I use the 5" inch RAM stem, which gets the camera high enough, and also allows plenty of horizontal/vertical positioning. I put a good UV filter over the front of the lens. I also use the Sony Wide Angle adapter to capture more of the things off the sides of the road. The rubber ball mounts absorb some of the vibration, plus the camera has image stabilization, which helps a LOT.
Ideally, it would be nice to have my own website or host, but for now, YouTube will do.
I'm not even in the same league as a few of the guys on this site with this stuff, but it's still fun to do. The editing is where the learning curve for me is...I'm an old dog, and teaching me new tricks on the software takes a while to sink in. I have been doing Pseudo Professional still photography for years, but seeing/capturing things in moving video is new to me.
If I can answer any questions with my limited knowledge, just let me know!!

I was told by people who know, NOT to use a camera that writes to a hard drive or DVD storage, as they are not able to take the environment (vibration) of the bike.
