Have I missed something, is there a difference between 16x9 and 4x3?

4x3 multiplied by a constant factor of , say 4, gives you 16x12, or multiplied by 3 gives you 12x9. Its my understanding that 16x9 is the HDTV format where the older 4x3 is the one we are all familiar with.

16x9 is the aspect ratio of the display, in the US terrestial hdtv broadcasts the video itself is typically encoded at 1920x1080x60hz interlaced or 1280x720x60hz progressive.
