Now getting used to fitting Humax Foxsat Freesat HD boxes, where I
used to only fit $KY (Pace 2600C1) SR Digiboxes. Have noticed that the
picture quality on some if not all, HD LCD TV sets, looks horrible
when showing SR channels, looks slighty out of focus. Where as a
standard resolution Digibox picture, looks acceptable. What am I doing
wrong?

I imagine it's down to the different resolutions that they're outputting.

Assuming they're all using the HDMI lead (and not Scart for SD channels and 
HDMI just for HD) then remember that each box could be outputting a vertical 
resolution of 576, 720 or 1080.

Two things come into play here...

The further the resolution is from the TV's native resolution, the more 
blurred it will look. This can be seen better if you take an LCD monitor for 
a PC, that has a DV-I connection, and change the resolution away from the 
LCD's native resolution. Increasing or decreasing the resolution makes the 
image look blurred.

The second thing that comes into play is again the resolution, but for a 
different reason. The higher the resolution, and higher the quality of the 
various connections (i.e. Scart versus HDMI), the greater the ability the 
equipment has to display how bad the original broadcast looks. A good 
example of this is if you look at a poor quality broadcast on analogue TV, 
it looks ok, but watch that same program in an HD channel, and it'll look 
horrendous. Or, another example is if you look at a video recorded on a 
mobile phone - it looks fine on the phone, but display it on your PC in full 
screen and it looks awful.
