Hi KMDonlon, is there any setting in the dvd player, such as it's own bass mgt? I know my Denon has a plus 10 db setting to help with the dolby processing. I'm sure Gonk must have suggested zeroing out everything in your dvd player,I know in my case the bass is a little more prominent in 7 channel stereo and almost nonexsistent in 2 channel and upsample.
