I'm contemplating whether or not to begin building a "collection" of DVD's now. I have a few DVDs now (14) and like the idea of building a library of my favorite films. But when I think about the long term though, I know in 5 years or so I'll end up having to replace my entire collection with HD-DVD, and that I don't like. So I'm thinking about holding off until HD-DVD comes along to build my definitive "collection." But then I think, what if like VHS and DVD before it, some new technology eclipses HD-DVD ten years down the line? Do you think that's possible? I tend to think HD-DVD will be the end of the line for home theater software, but I'm not sure. What do you guys think? Could it get any better than HD-DVD?
