AACS is the copy protection used on both formats.  Break one, break them both...

Little OT  :soapbox:

Funny thing about the DRM applied by AACS is how the key revocation works. As soon as I read the paper on the encryption scheme, I knew this would be blown away in a few ways:

* There are software players out there. The keys have to be somewhere unencrypted for the software player to get the data in and out. Find that location, find the title key.
* Politically, if they start revoking title or player keys, they're going to end up with a lot of unhappy customers. Imagine one day that someone brings over a disc to a friends house, and it won't play because the title was revoked and it's a new player. Or you bought that nice new $600 player only to find after a few months none of the newer releases play in it because the player key was revoked. Class action written all over that.
* The BD+ scheme won't even be put on discs for years... if at all. Sony: "We found AACS to be easily breakable, so we're going to use this one now..." Another scandal.
Good grief. DRM will eventually die on the vine. I'll be tap dancing when that day comes.

You and me both.

I'm in the middle on how I feel about the performance difference between DVD and Hi-def discs.  While there is a difference, and it is noticeable, it is important to remember that we're comparing DVD and hi-def content, not SD television broadcasts vs. hi-def content.  DVDs display a much higher resolution picture, with great color and little/no compression artifacting compared to TV broadcasts or VHS tapes.

While there is a jump in quality from DVD to HD-DVD or BluRay, it is nothing like the jump in quality we saw from VHS to DVD.  First, the difference in picture quality isn't as dramatic, but also, and perhaps more importantly, is that the DVD introduced other convenience-based improvements over its predacessors.  For the first time we had menus on our movies.  Rewinding and fast-forwarding was a thing of the past.  Slow motion and pause suddenly worked exactly as they should.  We had chapter selection screens and bonus content that didn't require watching the entire movie or fast-forwarding to the end to access.  The picture/sound quality did not age, degrading with use/time.  The media was MUCH smaller and less cumbersome.  Surround sound. 

The jump from DVD to HD-media offers only comparatively minor upgrades in video and sound quality.  We get a bump in resolution, but unlike VHS, DVD already looks quite great on a hi-def set.  And we get a bump in sound, maybe more (but certainly nothing like all) HD-DVD and BluRay discs will support 7.1 audio, but 7 channel doesn't sound THAT much better than 5.1, nothing like the difference between VHS's stereo and 5.1.

So, while I acknowledge a difference in quality between DVD and hi-def that is detectable to the non-videophile's naked eye, I still don't think any of the HD formats have a very strong sales-pitch.  They will supplant DVD eventually, but it will be extremely slow -- nothing like what DVD did.

Personally, I don't care.  I'll buy upgraded equipment when my current equipment dies and the upgraded equipment is reasonably priced.  I won't upgrade anything intentionally before then.  I just got my first HDTV a couple of months ago and that was only because it was a 32" LCD for $540.  I am in no hurry to spend a grand to replace the SD Tivos and swap out my satellite dish, nor to replace my DVD players or televisions.  I suspect there are quite a few people in my place for each person that would run out and spend tons on new formats and equipment just because it's out there.
