TV Broadcast from the World Taekwondo Championships in Beijing can be viewed on Eurovision according to the following schedule: May 18th 2007 - 0955-1230 - Day #1: Semi-Finals & Finals May 19th 2007 - 0955-1230 - Day #2: Semi-Finals & Finals May 20th 2007 - 0955-1230 - Day #3: Semi-Finals & Finals May 21st 2007 - 0955-1230 - Day #4: Semi-Finals & Finals May 22nd 2007 - 0755-0930 - Day #5: Semi-Finals & Finals
I've just checked the schedules and it is showing live TKD on Eurosport 2 at 11am on 18th May so it looks like that is probably it.
