Seems quite likely, in my opinion anyway, the issue is with the conversion of SD into HD to load onto their systems, and for some reason it's de-interlacing and zooming into the picture.

Many CRTs, especially older ones, had large amounts of overscan, so the graphics safe area was quite generous to make sure it wouldn't be cut off, there's no way some of the first and last letter of that caption wouldn't have been cut off on most people's TVs if that screenshot is how it actually was.

The credits on today's Casualty were further from the edge of the screen than before (though that could have been variation with the caption generator when it was made), the copyright strap was still virtually at the bottom of the screen though, and it was still filmised.

The zooming is admittedly a lot less noticable than the filmising, likely due to the fact most people will be watching without any overscan, and nothing important will be in the area that is cut off due to the producers compensating for overscan at the time (if you're watching on a TV with overscan added to the already zoomed in picture on the other hand...), it's still something that you'd expect to be picked up though. Regardless of whether the problem originates in Red Bee, UKTV or SES's hands, these are all major organisations who should be versed in proper technical standards, issues like this shouldn't be ongoing for months. Even if UKTV are technically right when people have contacted them about this that the issue isn't in their hands, you'd still expect them to spot there's a problem, find out where it's coming from and get onto whoever is responsible to sort it.
