box sometimes freezes when switching off

Hi all like it says only really started today not every time but quite a bit i go to switch box off with remote red button and it just freezes only thing you can do is switch off power at the back and then on again seems to solve it for a while but has been doing it on and off all day anyone had this problem

hi think i have solved my own problem so just for info seems if i only half press the standby button on the remote when switching off it locks up no probs if i press it properly
