Hi Chick,
You might find this explanation by Gordon useful: Using the actual hotpot or the generated htm file better?
I've uploaded a new version of your exercise which uses Dewplayer: Should students be paid to do well in school? Dewplayer
This is so that you can compare the different possibilities and make your own choices. I usually use Dewplayer for longer texts because there's a pause button so students have more control over the player.
You control which player Moodle uses when you create or update the Hot Potatoes Quiz: see screenshot below.
Because I've chosen:
Force media plugins No
Moodle uses "my" Flash player, in this case Dewplayer.
Cheers,
Glenys
