ITV Player

I am new - installed Serviio last night on my Windows 7 PC (with Java v6);downloaded ITVPlayer.groovy; and saved it in the Serviio plugins folder.
In Serviio Console, in the library tag, I then opened Online sources and added:
Source type: live stream
Source URL: http://www.itv.com/itvplayer/
I check stream URL and see an 'X'
Any suggestions (apologies if this is posted incorrectly)? I've tried Web Resource rather than Live Stream, but in the Media Browser I find no content. If I add the above Source URL in the Media Browser I get to ITV Player.
