I take back what I said earlier. There are several ways to get the screen to 
turn green, depending on which order the commands are run in. I've had 
instances where the last command run before the screen turned green was

> sudo ./rhd_dump -w 0x7454 0x80283D7A 1:00.0

or

> sudo ./rhd_dump -w 0x7458 0x00000010 1:00.0

as well.

As far as I can tell, MPlayer is playing the audio at the correct speed.
