Error code T6030 - audio / visual outputs problem
If you get this error message, one of your connected audio/video outputs is not supported. Firstly, please remove any additional audio/visual outputs and try again.
I’ve removed audio/visual outputs and still can’t watch
If you’ve removed all connected audio/video outputs and the problem still occurs, please update your graphics drivers.
Once you’ve done that, check to see if you’re able to watch NOW TV.
If not, and you're a Windows user with IE, you could also try uninstalling and reinstalling Silverlight.
