Thanks for this, William.
Here's my question about the new Dolby Surround approaches in these AVRs, though: Will the receiver remember what mode you applied for a two-channel signal the next time you play such a disc AUTOMATICALLY? In other words, right now when I view a DVD with a two-channel Dolby Digital soundtrack, my 605 automatically applies Pro Logic II to correctly steer the content into appropriate channels (dialogue in the center, et al)...but with these new models, you have to physically press a button on the remote when one of these signals begin playing, correct? If so, does the AVR REMEMBER to switch to the proper Dolby Surround mode you chose the next time a two-channel signal is detected?
My Panasonic UHD Blu-ray player is not running through this old receiver -- I am passing audio and video separately via two HDMI outs at the back of the player, one direct to the display for video and the other direct to the old AVR for audio.
