HD-DVD paper packed with Blu-ray Planet Earth

[Garconis]

I just got Planet Earth in the mail today, and inside of the wrapped case, was an "IMPORTANT NOTICE" print-out. It read:

"This HD DVD disc is manufactured to the highest quality available. It is possible this HD DVD disc was manufactured after your HD DVD disc player. To ensure the best possible viewing experience, you HD DVD disc player may need a firmware or software update. Please consult your hardware manufacturer's website for the latest firmware or software version and, if an upgrade is available, we suggest that you follow its installation instructions. For additional information please go to www.thelookandsoundofperfect.com"

I figured that when they said "HD DVD" they just meant a high definition disc, but that link is for HD-DVD's website. Strange.
