I mounted this Sony DCR-SR47 video camera I got recently on my bike last night to test it out as I'm riding through Rocky Mountain National Park today. I'm glad I did, because this camera records to HDD (Hard Disk Drive) and the vibrations of the bike cause it to stop recording pretty much at every bump.
I have another Camera (some kind of Olympus) for still pictures that also can shoot video, like 45 minutes per 1G memory card, and that has worked fine on the bike in the past, but as it's a still camera, the video isn't great. But it records fine despite the vibration.
I just wanted to post this because one of the reasons I got the Sony was to shoot video on the bike and it probably would work well with solid state memory cards which it can also use (no moving parts to vibrate like in the HDD), but I thought I'd pass this on for anybody considering a HDD video camera for riding videos--probably not a good idea... unless you mounted it to your helmet somehow.
I know there are little lipstick cameras for helmets and so on, but I needed a video camera that could shoot regular stuff too, and couldn't afford to spend the money on a specialized camera just for riding...
LOL now all the people who are camera experts are gonna say, "well of course HDD won't work on a bike you fool!" Oh well live and learn. Thought I'd pass this on anyways and maybe save somebody some disappointment.
