Since I bought this one as soon as it was available, no doubt I own the 'flawed' version, but with older equipment, didn't notice anything was amiss. In toggling between the DTS and DD sound, there is a slight volume shift, but it isn't of much significance.

Ed, if you had the the Denon receiver/dvd player combo(3805 receiver,3910 dvd player) like I have that reads the flag on the Dvd and does a 30 db lower shift, trust me you would definitely have noticed. I'm not sure what I was thinking when I did the switch back to Dolby Digital after cranking my reciever to listen to the Dts(and I still didn't even have it to a proper listening level for Dts). I ripped the Dts track's to see if it would work but the flag must be imbedded in there some where as still doesn't work properly(even on burned disk), very frustrating.
