btw, DRM hasn't historically been anti-piracy. It's been to stop the consumer from using the media as they please. While Joe Shmoe couldn't copy his DVDs to VHS for the kids, or even skip advertisements on a DVD, criminals were pressing thousands of copies, bypassing these restrictions easily. DRM controls the public, not the pirates.
In the case of music downloads, DRM has already failed and is being dropped label by label because it's bad business. I hope video goes the same way.
