Halo 2 for example, is being spat out in 480p. The FIRST time i had it going it was fine gamma wise, but since then it seems to have decided to drop the value. It 'feels' like gamma to me because adjusting brightness and contrast on the TV set itself only bleaches the picture. If it was a PC game I'd be straight to the video settigns in the game to up the gamma. How are people dealing with this? Is there a known hex edit available for each game?
