From: Marcin Rudowski <mar_rud@poczta.onet.pl> Date: 1142132627 \-0300
This patch fixes default values for some picture controls: - brightness set to 50% by default (now is 0%) - hue set to 50% by default (now is 0%) - sets saturation to datasheet value - volume set to 0dB (now is -32dB) and some left small fixes: - twice offset adding - balance didn't follow datasheet (bits[0:5] = attenuation; bit[6] = channel to provide attenuation)
