I am looking for a dvd player with a dialog enhancer that boosts the center audio channel in 5.1 so the dialog is more clear from 2 tv speakers. I know the Pannys and Toshibas have this feature but I don't like the new Pannys and am not too hot on Toshibas either. Are there any other brands that have this feature? Or how about a stand-alone box that will do this with any dvd player? Do they even exist? Thanks.
