Forgive me if this isn't exactly correct; I'm at work and I don't have access to my setup at home.
1. Copy the media folder from HyperSpin into your layouts folder in Attract Mode
2. Select "media" as your layout in HyperSpin
3. Be sure the system name in Attract Mode matches the system name in the media folder from HyperSpin
I'm fairly sure that's the gist of it.
