Mike, Thanks for you reply. If you can put this feature request somewhere down the bottom of the list, I'd appreciate it. I will look into extraction of frames from the stream as an alternative, I was really just trying to get existing bits of kit hooked up to a debian NSLU2 or my Linkstation to capture an external video source (x18 zoom old video camera) for a wildlife stills webcam. (As an aside, can you recommend an alternative analogue USB frame capture device that is well supported with linux drivers?)
