I had no problems before the firmware update that I could detect. After I did the firmware update, I had to hard reboot, because my receiver stopped detecting a DTS signal from any file with DTS audio I would play. At the same time, some of my external hard drives were not detected. I turned off the receiver, unplugged the HDMI cable from the TV, leaving the main monitor hooked up, shut down the Mini, turned on the receiver, powered the mini on. Once it was up, I plugged the TV back in, and DTS worked again. The drives were also detected.
I am posting this in case anyone else runs into these issues.
