From a previous post on another thread...
I am in favor of adding a day/night gamma control of some sort, if it is feasible.

One more thing. When you are playing a movie, it sometimes will play without showing video, and you have to toggle between the information, the music icon, and finally to the video that is playing. Is there a possibility of disabling everything but the actual video in that "tab"? For home use it isnt so bad, but in a car every click is important
