Sam, I just posted a question that is similar to yours. My issue is about how SmartHub continually throws up pop-ups whenever it does some kind of update to SmartHub. I hope we get traction on our questions since they are both related.
Recently I've been using a USB HDD as a backup recorder for DVB-T2 on my UE46D6530.
Unfortunately, somebody thought it was a good idea to plaster a huge "NOW RECORDING" notification in the middle of the screen, which is incredibly annoying every time a scheduled recording comes along. I have to reach for the remote control to press OK and then it automatically changes channel to whatever's recording, even though I'm watching something else on another HDMI connection.
There must surely be a way to silence this irritating pop-up? I don't need to know that something's recording, I just want it to record. It's driving us nuts! I don't want to have to install third-party firmware just to get rid of it. Hoping for some kind of manufacturer's menu that has the option to disable!
