Apologies for posting another techie question which should probably be directed at a specialist forum, but seeing as the Sony HX750 DVR seems to be a popular enough model in Ireland I was hoping to find someone who has successfuly set up their Guideplus on it. I managed to do this fine on another model a few months back but the Guideplus set-up is quite different on the Sony. I'm fairly certain I have everything right up to the point where I choose my host channel settings. (eg I've told it I'm in the UK, I've put in a Belfast postal code, I've selected NTL Cable and Sky Digital in the settings, even though I only have NTL, etc. The DVR is able to change channels when it sends a signal in the set-up process, which suggests everything's fine up to this point).When I go to the host channel set-up section I'm asked to choose a 'Source', either Tuner, Ext Rec 1 or Ext Rec 2. I actually haven't a clue what I'm meant to choose here, but I've tried all three! I know I have to use ITV as my host channel - when it asks me to choose a 'Programme number' do I put in 3, ie the position where I've put ITV on my DVR/TV? If not, what number do I put in? If there's any one out there who's solved this problem I'd love to hear the solution - thanks!
