pervy snape-fancier

A while back I pre-ordered the Blu-ray versions of the "Ultimate Edition" or whatever they're calling it of Sorcerer's Stone and Chamber of Secrets. In the process of proving last night that the thing in the Fry's ad which showed a set of all five films on Blu-ray was not this edition, but just a boxed set of the films, I noticed that the "Ultimate Edition" is also available on DVD for about ten bucks cheaper.

I thought well, there must be something extra on the Blu-ray version, or maybe I didn't know I had a choice. I looked at both pages on Amazon, though, and aside from the fact that the Blu-ray crams both the theatrical and extended cuts on a single disc whereas that takes up two discs in the regular DVD version (3 discs and 4 discs total, respectively), I couldn't see any difference.

The television that is hooked up to our Blu-ray player (read: our PS3) is, um, kind of the opposite of HD, so while we can watch Blu-ray discs we don't get to see any of the actual benefit of buying in that format. So unless there's something different about the content, there's really no reason for me to pay the extra money.

Can someone reality check me here, and make sure there's not something I'm missing? Because if not, I think I'll cancel the Blu-ray order and go for DVD instead.
