Yellow should be the brightest color of all colors.

Take another look - note that there are two exposure levels on the blue due to the shutter of the camera and the short persistence of the blue phosphor. The darker area across the bottom of the color bars is closer to correct. Note also the excess blue at the very bottom of the gray steps.

However, green is still fairly dark. - This could be a combination of low Q gain (or high I gain); the response of the still camera; the matrix in the still camera that converts its raw sensor output to sRGB (which has a smaller gamut than NTSC); or some other factor, like clipping in one of the matrix stages.

Note that the cyan is quite bright (brighter thatn the yellow) even though the green is dark. This leads me to suspect that most of what we see is due to the still camera.

Pete - Some things you could try: you could set your camera for a slower shutter (like 1/8 or slower). Also, you can check if the green appears this dark and the cyan this light to the eye. Also, you could check the relative gain of I and Q.
If you look at the R, G, and B outputs with a scope, you can check for waveforms that are nice and flat and equal-height sqiare waves.
