The customer reviews on Amazon are filling up with people complaining about the DRM on Spore and giving it 1 star (although 90% of them are by people who haven't actually bought the game).
Personally I didn't have any problems with the DRM (which is not to say I won't in the future). The game itself however was a bit of a disappointment.
All those people having trouble viewing the video in Firefox, you're not running AdBlock Plus by any chance are you?
I found it also didn't work in Firefox, but I could download the flv files no problem.
As soon as I whitelisted tvnzondemand.co.nz the embedded player started working.
(There is of course a rather obvious downside to this workaround.)
