Actually that game, and the one before it South Africa vs Iraq,
were both shown in Stretch-o-Vision. I Checked on the Analog channel and they they were both showing the same image. If It had been in HD, the Scorebox would have been in the middle on the HD channel.
Here's screenshots of the game were they showed an HDTV they have at the stadium. One of them is the original broadcast, and the other is edited to be 4:3.
Notice how the HDTV is much wider in the 16:9 image, and also if you look closely, you can see that the scorebox is in the middle. Also on 4:3 image the Referee doesn't look out of proportion.
Also during the New Zealand vs Spain
game, both TV Azteca, and Televisa tried to make game HD, and they couldn't. The both flipped the switch, several times, but the game still stayed in S-o-V.
