I can't answer your question, but I noticed this when I upgraded my EPGGrabber to the latest version a few weeks ago. I had MP configured to output episode names and numbers and suddenly there were numbers appearing beside every programme title after the EPGGrabber update. I had to change MP to output Episode names only. Only TV3/FOUR appear to update these names for some programmes.
From memory they were quite long numbers and didn't make sense to me, but perhaps they are unique numbers for each programme, which could be useful to prevent duplicate recordings, etc, if MP supports that.
