It is actually one of the drivers I use most when testing something, as I have a lot of those devices (although I don't have the specific models you have). That said, the green bar on your video usually happens on two situations: 1) If you have a PAL input, but you're capturing video at NTSC; 2) When there's not enough bandwidth at the USB bus for the video. Analog TV capture, at 640x480, usually consumes 60% of the available bandwidth for ISOC frames on a USB 2.0 bus. Maybe you don't have enough bandwidth, or your USB controller is broken. Ah, one last thing that occurs to me: some domestic RF generators found on video games and on other CEC electronics sometimes produce outputs that don't quite follow the TV standard defined by ITU-R, causing troubles for analog TV decoders to identify it. Maybe that's the case. If so, try to capture from some other video source. Thanks, Mauro
