And for anyone wondering what "PrevVisuals" normally does...

1. install Hijack, start up a playlist, and press INFO on the remote until the INFO:Off screen is displayed.

2. Now, perform a single short-press of the "Visual" button on the Rio Remote. This should bring up a small "Visuals" pop-up window. While this window is displayed, the PrevTrack and NextTrack buttons (and/or the knob) can be used to cycle back and forth through the available Visuals choices.

Cheers
