Thanks Carlos for the "initialize" tip. That did the trick regarding keeping the clock on time. As for mircast and DLNA, I still cannot seem to get it to work. Is it some software restriction because this is a US model? I did (very briefly) get screen mirroring to show, but then it went to the "Waring, do not watch TV while driving" verbiage on the screen and that was all she wrote.
Any advise would be helpful.
