I live in Dubai and all content comes through pay TV via their box which is hooked up at the rear. This external Input is shown on screen as VIDEO 1. There are preset equipment labels which can be used to assign a name to any connected equipment and which can be edited but this capability doesn't extend to the input device itself. What with Arabic subtitles which also can't be made to disappear, it's almost like watching the screen through a hedge. Any solutions?
