I have rung the aerial guy back and will see what he can come up with.
Regarding the comment about the upgrade from 1.04 to 1.05 possibly showing the signal strength indicator lower after the upgrade - it was just an observation and I hadnt measured it - It didnt make any difference to the picture quality (or pixelation that I am getting) so I am definitely not pointing fingers at anyone.
Great news about being able to record from this box at some stage in the not too distant future - I biffed my VCR in the rubbish a couple of years ago - Would be handy to be able to record TV once in a while.
Did anyone else find the subtitles out of sync? or is it something to do with my poor signal - I recall the subtitles were displayed around 2s before the speech.
