Mike,

I support your preference for 3, but I also share the concerns for still more key-presses before we can start playing whatever selected.

Haven't thought this through, but it may help that, instead of confirming a selection by pressing the OK-button, the present selection is confirmed by an immediate press of the button that selected it (say within 1 second). This would prevent a lot of navigation on the key-board of the remote AND allowing us to keep our eyes on the road!
