Wrong 'mini dvi to video' adapter for my 12" Powerbook 1.33

I recently bought the M9319 mini dvi - video adapter for my 12" Powerbook 1.33 to find that the mini dvi on the adapter is a different size to the one on the computer and the adapters supplied with the computer.

I've been doing a bit of research into this and it seems a bit of a grey area. Apple have not made it clear in advertising this product that it is only suitable for the newest 12" Powerbooks and even state that it will work with a 1.33 machine in their following article:

Has anyone had a similar experience, or suggest an alternative product that will work? Did Apple make an older version that works with the 1.33?

Any help would be much appreciated. Thanks, Graeme.
