I have had a new problem with the 1070 that I don't understand. Sometimes when switching between sources the 1070 just freezes. It will not do anything until the power button on the back is turned off and back on. It will not even go to sleep when the front powere button is pushed. This started happening as I began programming a URC MX-850 remote. I suspect it has something to do with the timing of commands send when a macro is running, but haven't been able to isolate the problem. It appears to happen when switching between sources, i.e. digital tv tuner and DVD, which uses analog audio inputs and HDMI-DVI video.
