Does anyone else get the Pro box freeze up if they turn off power at the plug, turn back on then turn on the box. When I done it the channel it starts on freezes after 5-10 secs. The only way to unfreeze is to change channel. Incidentally I get a message saying there is a problem with by broadband affecting this channel. I rebooted hub and made no difference still had to change channels. Box is in internet mode so no aerial connected. I have tried it a couple of times and same results.
