This usually happens when recording.
What happens if you try changing channels using the up/ down button? Is it still frozen on the channel?
If you weren't recording I'd suggest resetting the box which will reinstall the software and hopefully clear any bugs.
To do this, press the button on the left hand side 5 times in quick succession with the box on and it will restart, or use the factory reset option within the settings menu.
You will lose any recordings though, if you have a usb stick installed.
Hope this helps.
