As soon as you get an Input/Output error, the bug doesn't come from aMSN but from the driver and I won't do anything to change that ! I use uvcvideo with my Logitech QuickCam 5000 and it works perfectly with aMSN. So driver is the same and software is the same : the bug is in the driver. Don't forget that a driver is an interface between software and hardware so it must act the same even if the hardware changes... Phil
