We have 2 XL4 boxes connected to a Comcast cable. For several years, they worked more or less as advertised. Over the past several weeks and especially the last few days, one of them seems to have lost its mind. The other box is working normally. Here are some of the bizarre behaviors: It will frequently hang or freeze. The screen goes blank (black) and the only button that works is On/Off. The 4 red recording lights go on and off and I think it is working behind the black screen because when I force a reboot, shows will have been recorded. I have waited 12 hours or more to see if it will come back to life, but it rarely does. I end up unplugging it and then letting it restart. This would happen once or twice a month, then 2-3 times a week. It just happened 4-5 times in the past day or so. It is in that state now. Sometimes, instead of freezing, it will spontaneously reboot. This happens less often that freezing, but still a few times a week. When I delete a show, sometimes it will continue to be listed with an "X" next to it. This can last for up to a day or so. Sometimes, a show that I know was recorded will not show up in the list. Then sometime later, especially after a reboot, it will be back. It there anything I can do about this?
