When I use the Video Plugin with a usb machine camera in Mach the X & Y axis become unstable and start to jitter while making a move. The only way to get the X & Y axis to move properly after using the video plugin is to exit Mach and restart Mach then everything works fine until I use the video plugin again. It appears like there is some sort of a driver conflict on the usb side of things but I cannot see where the conflict is. The machine camera did not require a driver to work in Mach, just had to plug it in. Has anyone else run into this issue, if so where do I start looking to cure the problem?
