A few months ago I finally updated to HD TV. The picture quality is fantastic however, the dialog on most movies and DVDs is so low that I have to turn up the volume to hear it and then turn it back down when music or action is present. (same problem with my old TV) What is with modern technology? can't they get anything right? I do not have a home theatre system yet and am reluctant to get one if it won't solve the problem. I understand this is a common problem, any suggestions? TKS
