I've been doing some testing on a new 4k TV and it seems to offer the best SD scaling when the resolution of the box is forced to 576i - if I use the automatic resolution settings it scales the 544x576 channels to 1920x1080i first which the TV then has to rescale again.

I found info from this post explaining why it's done:

The picture quality does seem to improve for me when letting the 4k TV scaler in this set do all the work.

Is there anyway of overriding the automatic resolution setting for the lower than <700 pixel wide channels please so that they can be left at 576i while still being able to watch the HD channels in full HD?
