I have Windows Media Player 11.0.5358.4827 on an WinXP PC and when I
attempted to play BBC Planet Earth (new out of the box) I got the
message

Windows Media Player can not play the DVD because a problem occurred
with digital copywright protection.

I tried the same disc on a (friend's) Vista PC with Windows Media
Player 11.0.6000.6336 and the disc plays fine. How can I play this
disc on my PC? I have played many newly-released DVD movies on my PC
without any issues, so I'm wondering if there is something special
about Planet Earth's discs? Or, do I need to upgrade some software
on my PC?
