Since the problem is happening on Analog output, one possibility is that you are hearing clipping distortion due to the output voltage of the player being higher than your preamp can tolerate. If you are using positive valued speaker volume trims in the OPPO this becomes more likely.
To test this, set the OPPO to Volume = Variable, play one of your problem tracks, and lower the output volume of the OPPO a lot using the Volume +/- buttons on the upper left of the remote.
Also double check that you are cabled to the correct output sockets in the player and input sockets in the preamp. Since the problem is happening with 7.1 content, pay particular attention to the two REAR channel cables.

Bob, thanks much for the reply. I will call OPPO and also try what you suggest. However, understand that 7.1 analog input is fine with SACDs, BD concerts and BD DD and DD-TrueHD (although the player did not recognize DD-TrueHD, only DD, on Batman Begins). The problem seems only to occur on BD DTS-HD playback. The pre/pro is a Sunfire TGP5, which is a pretty good mainstream unit. All of this makes me doubt it's an output voltage problem, but I will try your good suggestions nonetheless. Much appreciated!
