Does anyone else have crappy quality with the OS X DVD player? In full screen, it looks worse than a DVD on a TV. Things that are supposed to be black are purple, and the picture is pixelly. The bad picture extends a little into the black bars for widescreen. Menu action is bad; the moving object gets split up into horizontal bars and then every other bar is out of sync. Is there a better DVD viewer or some setting like a checkbox to uncheck labeled "suck"? I know that I have to turn off the "sound enhancer" in iTunes to get sound quality to normal levels; is there a setting like this for the DVD player?
