Channel 4 live have started to track the location settings on your computer in addition to the IP address.
The fix is quick and easy;
- set location in Control Panel/Regional Settings to United Kingdom
- set time zone to GMT-0 (London, Dublin..)
- check if the clock shows correct time for GMT-0
- restart the computer (this is significant for some reason)
We would also recommend that you go into the privacy settings on your browser and disable location tracking.
If all of this is too much trouble, don't worry you can also watch Channel 4 live at http://www.tvcatchup.com/channels
