The PiVideo output is quite odd, perhaps as a result of communications errors. It reports that there is no active video detected – is the blue LED lit when you attempt the capture? If the blue LED is not lit, you will always receive an MMAL error.
Does PiVideo give the same output each time you run the “-q all” command?
It would be helpful if you could describe what the status LEDs look like with video input connected.
Also, please not that you should specify “mode 6” video (640×480) with the SD1 board. You will get unpredictable results if the camera mode does not match the resolution of the video.
