OS: RedHat 7.3 (kernel 2.4.18) Camera: Logitec QuickCam Pro 3000 Application: CamStream (http://www.smcc.demon.nl/camstream/) The video size cannot be changed. I also tried to write a program to change the size of the video, it just didn't work. I guess this is some problems with the driver. Any ideas? Thanks in advance, Dean
