I am just catching up here after spending the day in meetings, but as I read through it I had the same thoughts as Jason - specifically because I've heard instances of clipping, static, distortion, and other audio artifacts before that were inherent to the recording and appeared at any volume. Having a better than average sound system actually makes these artifacts worse because they become more noticeable as the signal path becomes more transparent. I've rarely encountered it on DVD's, but I've noticed it any number of times on TV.
