Do you still call it a DVD?

I just bought The Avengers on DVD. Well, that's only partially true. There's a Blu-ray in there as well, but I don't know if I'm going to use that term for it. I like the term DVD, and even though "technically" a Blu-ray is different, my brain files it away as DVD. That's just what is is. A CD plays music. A DVD is a movie. My brain has no need for another term for what is essentially the same thing. You put a disk into a player and a movie comes on.

Yes, all you technically savvy people will be able to fill me in on how exactly a Blu-ray is different. (Not to mention different from the HD-DVD.) I know all this. I know about storage capacity and high definition and things like that. I get it. But you have to understand, it's still the same size and shape as a DVD, so that's what I'm going to call it. True, the case is slightly smaller, but when I want to put in a movie on a disk, it's going to be on a DVD. I might eventually come to terms with the new terminology, but for now it's just one extra step in my thinking process that just isn't needed.
