If you are watching TV and press left or right, it is volume, If you press info the channel name etc comes up, NOW if you press left or right at that point you get the other channels (virtual zap)
I no longer have a dreambox but I think with this image you can go to settings, key setup, and now you can change around buttons. Higher up on the remote under the numbers there are 2 other arrow keys, I think these can be changed to virtual zap, or volume. Then you do not have to press the info key before the arrows.
also in the key setup you can change the colour buttons menus. When you press red you get the various channel options. Teh only one I use is the second one, show all channels. So you can turn off all the other functions on that menu. Now this means you only press red once and the big menu comes up.
The gbox functionality is now working on my dbox2 with andromeda 2.0, big thanks to Xenafan & cryogenic
