Excellent as ever Tony, I was just digging out the hex editor so I could find out what the Rio logo looked like on the player.
The answer is that it doesn't really work very well, because it is all the same flat shade (so it highlights the banding on the screen).
But, I now have a Rio Car, serial number 47...
(it even says so in the about box on the player)

Unit serial number 47 (was 330 in the queue)...
