I got a new DVD player and now when I watch certain DVD's, I see more/different stuff? What's up with that?

Question

I tried a DVD that I've played many times before on my previous player. But in my new player I now see little bits and pieces of stuff that I hadn't seen before. The new player seems to be accessing stuff on the DVD that the other player didn't. I've noticed the same thing on several DVD's as well. It's cool but it's very strange.
