I bought a Pioneer Elite BDP 09 here on Audiogon and had no problem playing CDs and DVDs. However, at some point I tried to play a Blu-Ray disc and the screen was blank. I called Pioneer and they walked me through the diagnostic, only to find my player did not have the "latest firmware update." They sent me an update disc (without charge) and once it was uploaded, no problem!
I can't comment on the Dolby Atmos issue. My best advice is to call McIntosh and talk to a tech. They have probably heard everything and can help you troubleshoot the cause and find a solution. Best of luck!
