So far, I've had this receiver for 2 days. I haven't been able to fully test it. I tested my Dune D1 media player, and it worked without any issues. Thereafter, I upgraded to the latest firmware. I re-formatted my corsair 32 gb flash drive to Fat32 even though it was already Fat32 (recommended). Downloaded and unzipped the files. Hooked it up to the AVR, and approxiately less than 10 min. it updated.
I was surprised that it turned off and did not turn back on after the update. Yesterday, I download the iControlAV2012 app to my wife's and my iPhone 4s phones. At first I kept getting an error message "error code b47110." After some research, I found out that the iControlAV2012 app will not turn on your receiver unless you have NETWORK STANDBY ENABLED. After I enabled network standby, I was able to fully controlled the AVR. I also signed to my Pandora account via the AVR's OSD. Pandora is fully functional, and it sound awesome

I will be off work this weekend, and I will try to run MCACC. I would like to also say that my new Polk Audio 25C sound AWESOME!!! I just need to raise my TV several inches since this speaker is pretty tall. I will be installing the iControl app on my wife's iPad. I also like the option that you can re-name the HDMI inputs! So far, I am very happy with this receiver. At first, I thought I was going to regret buying it.
However, it does sucks for those of you who have had issues with this AVR.
