Planet Earth: Blu-Ray vs. Discovery HD

[xpander]

Does anyone have any comments on the quality of the Planet Earth blu-ray versus the quality of what DiscoveryHD broadcasted?

I have the blu-ray version (which looks pretty good), but didn't see any of DiscoveryHD's original presentation (I know it's pathetic, but my cable provider doesn't offer any HD channels..)

According to highdefdigest.com, "the DiscoveryHD presentation was constrained by heavy compression, which results in tons of artifacts, reduced resolution, and macroblocking. Far superior to the broadcast version, both next-gen editions boast wonderfully stable video, no obvious compression noise, and certainly no pixel break-up."

I've seen other broadcasts on DiscoveryHD where the clarity was equal to, if not better, than Planet Earth. Just checking to see what anyone else thinks about this..

Thanks.
