"Err, is it because I don't think being able to change channels is much use if I can't watch them because I have to have my TV switched off to do so? "
Sorry to ask such a silly question but could you not see the channel number change? therefore seeing if it works from the greater distance. or even have it switched on with 101 ,switch off TV change box to 102 & switch back on again Clearly I am of a lower mind set & have missed something !!!?
