I am new to D and just had it installed 2 weeks ago, but I am having a problem with my HR21-100. When I go to power it on it does not startup, I have to either reset it by unplugging it or pressing the red reset button next to the card. It has happened 4 times already. Is anyone else experiencing this problem? Should I call D and get it replaced? My other boxes 1 which is just a DVR and the other 2 which are the standard boxes have no issues.
