Planet Earth HD DVD and Blu-ray sales soaring {Engadget HD}

Jun 8th 2007 8:54PM Seems like a lot of people are missing one important difference between the formats which is behind the higher sales for HD-DVD of Planet Earth; HD-DVD players currently have no region coding so the US Planet Earth disc can be bought say for playback in Europe for example, whereas the Blu-ray version and players are region coded therefore the Blu-Ray version is US only.
