The song starts with open G and open B for the first chord. The next chord is A and C. The next chord is G and D. And the guy on the DVD says to play G with a B instead. And that is supposed to be a moving third. But how do I know when to play G with a B on any other song because there is no sign indicating that it is a moving third chord? Does that make sense? I just don't really understand WHAT a third is and WHY I had to change the G to a B. And that's where I am lost. So if anyone can explain those two things to me, I'd GREATLY appreciate it! :D

You had to change G to B because D is the third of B: B-C-D 1-2-3

Looks like your moving thirds are just going straight up the G scale. G to B is a third G-A-B 1-2-3, then A to C A-B-C 1-2-3 (baby you and me, girl), and B to D is a third. G to D is an interval called a fifth G-A-B-C-D, so I'm not sure why that's in there...I mean, if the etude is supposed to be of thirds...plus you don't usually see hollow root fifth power chords in a classical setting...maybe it's impressionist? Romantic? Who wrote the etude?
