I am trying to do something very simple: play an mp4 movie file (only 1) from my SD card (SDHC) on my HD1010 model. When I turn it on, the Pwr light goes on, and the Bsy light flickers, but then it never displays anything on my HDMI-connected monitor. I don't even get the Brightsign loading bar etc.
Not sure what to do. I'm on a Mac and so the only thing on the SD card is the mp4 file. In the past, I had no problems playing it, so not sure what happened...
Should I do some kind of serious reboot?
