I'm having significant freezing issues with my HR34. This is my second HR34 and my first one was replaced due to the same freezing issues. It freezes about once/week and if others aren't experiencing this problem, I'm assuming it must be something in my setup? I have it connected to a Denon Receiver (AVR-2309CI) via HDMI and that connects to a Samsung DLP TV, also via HDMI. I'm running software version 0x54a. Anyone have any thoughts/recommendations?
