onboard camera sucky sucky

hey folks, i took delivery of a camcorder this week, its all gravy apart from the suction camera mount is causing a problem with me trying to do some decent filming, basicly the the viabrations through the car is causing alot of shaking so all the footage is very u guessed it shaking! so far ive mounted the camera on the rear window and rear quarter windows but things havent improved, even the camcorder has this anti shake thing and that doesnt help either

so on the way back home today i held the camera in my hand and did a bit of filming and the results were good with no shaking insight

has anyone come across a similar problem? and what have you done to eliminate the problem?

thanx

if the roads are anything like around here im not suprised it shakes its tits off. You'll probably find it'll be a lot better when your on track.
