It might not be just Sky Arts - although I rescanned a while back to fix the channels when that one 
changed. I am using SD-json, though, so my problem might be different and elsewhere.

I have noticed situations where, for example, it would not record an 'Only Connect' episode because 
it insisted that it was a repeat from last November; 'University Challenge' episodes where the same 
teams meet again in different rounds were ignored; a 'Most Scenic Railway Journeys' was new but 
flagged and described as an earlier episode. I had to manually over-ride all of those with prejudice 
to get a recording. There are probably other examples.
