Do you want a cropped 320x240 or a scaled down 320*240 video? If cropped, then S_CROP should let you specify the origin and width and height as 320x240. But if you want a scaled down version, you should capture full resolution video from the capture driver and then use resizer to scale it down to 320x240.
