I recently bought 2 Minis. One of them worked fine right off the bat, but the other one kept rebooting, or would boot to a blank screen. At first I thought there was something wrong with the unit, but when I hooked the other Mini up to the same TV, it exhibited the same behavior. This led me to the conclusion that there was some type of incompatibility between the Mini and my older Pioneer Elite plasma. I assumed it was an HDCP issue, so I stuck a Monoprice HDMI switch that I had lying around in between the Mini and the TV. Voila! Problem solved! The weird thing is that I had an old S3 hooked up to the same TV via HDMI for years and never had a problem. I don't get it, but at least I found a solution that appears to work. Just thought I'd pass along the info in case others are experiencing the same problem.
