Dumb question, I know, but I can't seem to find the answer even after searching the bbs...

I can't toggle left and right between the various menu options using my Sony stalk remote (plugged into the tuner module, and enabled). One of the buttons allows me to choose whatever existing menu option is already "highlighted" (shown in large print), but no button seems to let me select between them to get to the actual menu option I want.

For example, I can hit "enter" remotely to bring up the Playlists, and then hit "enter" again to make it play the first playlist that it highlights, but I can't toggle back and forth between the playlists to select the one I want first.

What am I doing wrong?
