I was having some saturation problems with my S2 when playing videos saved to my phone. I WAS saving movies to USBstorage, and opening them from there. There were no additional display settings there when playing the videos. But when i saved movies, or moved the movie to microSD card, the video then appeared in the Video app directly. When i opened the same avi this way, the additional settings were there. I got brightness, colour tone, and outdoor visability. My Settings are Brightness :3, colour tone :cold, outdoor visablilty : off , video playback is now superb! Also if you move your avi's to the camera folder they will also work in the main player from there.
