I was watching ITV HD (Central News) and that didn't have a problem, was only reading on twitter that there was problems with ITV that I knew about them, I checked and found on my setup it was just the SD versions out of action, the HD versions of ITV, ITV2, ITV3 and ITV4 were working fine, then later ITV themselves posted the HD versions were OK.
