I tried enabling AR - and results are negligible (but it wasn't a very detailed assessment tbh. Will make a more indepth assessment tomorrow).
Also - and irritatingly - the TV has a long pause and flicker between channel changes, whilst it readjusts to the new resolution
No - old software, but no harm in trying. Will have a crack and report back.
On a separate note, and for my own learning - why is it that the PQ on an E2 STB is not as good as the PQ on a non-E2 STB, for SD broadcasts?
