Having problems over here as well with chrome. I had problems with TVARK a few years back which only seemed to affect me, and it took me nearly a year to get it working properly.
I've been having the same problems since the weekend. I've been trying to play clips on the various ITV News pages - I've tried them in Chrome, Firefox and IE on Win 8.1 and none of them work.
It is specific pages. I just checked BBC One, and Australia's Seven, Nine and Ten Networks and they worked fine. ITV News though, yep, broken. First Report opening titles in the ITV Lunchtime News section gave a file not found error. Seems to be just ITV News and Australian Soaps.
