Sweet mother MacCrae! I've just spent the afternoon trying to download and update the TV via USB. It's never been an issue in the past, but the TV will not recognise the file and keeps going to the media options instead. Tried 3 different USB drives, but no dice, and it won't update over the net. I give up, far too hot for such shenanigans!
