Actually, pressing the green button before pressing the up or down button is a result of the BS3 programming rather than the Beo5. Perhaps the BS3 was connected to an HD DVD or Blu-Ray player? The BS1/BS3 is configured to work with certain HD DVD and Blu-Ray players so that pressing certain color buttons switches between "menu" and "transport" modes for the up,down, left, and right buttons. This is necessary because of the nature of HD DVD and Blu-Ray menu navigation while a movie is playing. Once you press the color button to switch to transport mode, however, you stay in transport mode and no longer need to press the color button until you switch back to menu mode. This would be the same with a Beo4. However, you CAN program the Beo5 with macros so that pressing a button on the touch screen will change to transport mode and skip to the next chapter. This is what I have done.
