Sorry I didn't see your original post in time. not an issue for me, though maybe for the GP, so take note, whoever you are. For my purposes, 1) not using ivtv and frankly putting real capture cards would probably be to much for these little mobo's -- now using it for a mythtv front-end that would be sweet (it comes with s-video out and ac-3 onboard sound) 2)I'm doing frame grabbing, but its through usb-webcams and gspca driver and motion -- seems to have a pretty short chain and I don't think it does more than encode with ffmpeg. I don't think it even transcodes as the resolution is set in the camera itself through the gspca drivers. at least that's how I understand it. thanks for the links though -- good to know as there's definitely some ivtv floating around in my house ;) A
