I'm pretty sure that this is a result of the channel in question being 
transmitted at a lower-than-usual resolution (E4, More4 and the minor 
ITV channels spring to mind) to cram ever more into the available 
bandwidth.  I assume the subtitles are transmitted with absolute pixel 
offsets to specify their position, based on a full PAL image (presumably 
this makes life easier for STBs).

I suspect the blue bar is another symptom of the same thing - my 
freeview STB likes to make green ones on More4 occasionally, and the 
'correct' fix is a bit of overscan.
