So I've been back with DirecTV for a week now, enjoying the service, etc. Used to have three HR-2Xs, now the Genie and two minis. But I've noticed that when I turn on a TV that's connected to a mini, I often get a white screen for about 5 seconds before the channel engages. Also have been having trouble with the EPG, with some channels showing, some channels not, sometimes the guide isn't there at all. Have to unplug the main Genie and plug it back in. Is this normal?
