ITV1-HD appears to have screwed up again, On my Foxsat-hdr ITV1-HD Granada the second part of Dancing On Ice was recorded on the end of Wild At Heart. Not a problem if you recorded both, presumably for others it may be a problem.
This must have been a Freesat only issue, as I successfully recorded Both parts of Dancing on Ice and Wild at Heart from ITV1 HD Granada on my Freeview HDR-FOX T2 box.
