buggdog,i doubt a firmware update would be a fix,i've found alot of times is was the way the dvd was mixed.i say was because my dvd died,now i do low listening to 'dish',high volume on 2(.1)ch listening.i distinctly remember different dvds(mostly concerts,music anyway),where there would be talking between tunes that would switch to different processing.next song starts there would be a 'dropout' while the processing switched from 'dolby' to dd or dts.hope i don't confuse you,just trying to help:)
