What's Tiger Studying On Tape?

Not to wear out this Tiger-plays-Oakmont thing, but a reader who would rather not be associated with this wretched site made this point: 

One thing left unsaid in the Woods item is that he obviously studies videotape of past events at a course before seeing it for the first time. That's the only way he would have thought about Oakmont as a tree-lined course and then have been surprised when he arrived.

To the inkslingers out there considering a Tiger question at Wachovia, how about asking about this instead of about the due date or the new dog.

What's he looking for on old tapes of majors? Has he learned stuff from video that has helped him in any of this 12 wins?
