Hi - I have just purchase an ATV 1910 and I'm having issues with my video signal on power up.  Every time I shut the unit down and restart it, my tv states there is no video signal via the HDMI input. After unplugging the device and power cycling it, the video signal is found and all is good.  This is extremely frustrating.   Everything else on the box is great and seems to work as expected.  I'd hate to have to return the box, but if I have to unplug and reboot every time I want to us
