So this has been happening off and on since I got the H20 back in December. So the screen goes black and the box reboots. It happens about once a month. So yesterday I was watching something on TNT HD and it did it again. Not that big of a deal. So around 8pm eastern I was switching back from and forth from CBS HD (D.C. Local) and ESPN HD for the Phillies game. It would reboot every 5 minutes while I was watching ESPN HD. It happened 4 times in an hour. But if I left it on CBS or HBO HD it was fine. Anyone ever have this happen before?
