It's the same on the ones I've done for EastEnders, Casualty and Kingdom as well.

I'm starting to think my suppossition there may be correct- that something went wrong that caused the picture on SD conversions to be shifted slightly lower on the screen than it should be (hence the black bar at the top of the screen on the affected shows for a couple of weeks), to "fix" this problem they just zoomed in until the black bar was gone (hence the loss of picture on the bottom and sides, but not the top) rather than actually bring the picture back to its correct position, and the de-interlacing got introduced into the chain at pretty much the same time.

So for months we've had a zoomed, blurred, de-interlaced picture on all new SD acquisitions as a result.

It's interesting that us on a forum like this can look at what's happened and try to work out what might be the cause (which would help in fixing the issue... if the people in charge actually admitted there was a problem to fix), while UKTV themselves are flatly denying they can see a problem at all.
