I have the AVIA disc and the only thing I've done with it is change the T.V.s picture, brightness, sharpness, hue and color. Besides that is there anything else I can do with the disc that won't require a professional calibrater. Seems to be the same with the sound. I havn't messed with it yet since I don't have a sound pressure meter but it doesn't look like theres anything else except setting all the speakers to the same volume. Any help, am I missing something?
