My remote control has just stopped working, but what it's doing is weird. When I press a button the light lights up at the front. I can control the TV with it fine but it just won't work with the Digibox. However, if I reboot the box then the remote does start working again, albeit intermittently. I have replaced the batteries just in case but this has made no difference. Has anyone seen this before? Does it mean trying to get a new Digibox?
