If you've found yourself yanking out your hair, wildly frustrated by the new two-disc Limited Edition release of Christopher Nolan's Memento, you're certainly not alone. Both discs, particularly disc 2, provide unique challenges for those of us who prefer straightforward DVD menus. In short, Nolan has made the most of the DVD format to create a fascinating--if somewhat maddening--incarnation of his masterpiece.

To ease your exasperation, I've compiled this Navigating the Memento Limited Edition DVD. With this companion in hand, you should be able to easily click through the psychological-testing menus to access the special features that you want.

Play Film
To play the film, select Watch.

View Chapter Menu
To view a chapter menu, select Chapter. You'll find a series of multiple-choice questions, but the answers don't matter. The answer key to the right, where you click your chapter selections, has only one clickable answer per chapter. So, no guesswork here. Just click the chapter number you want.

Choose Audio Options
To choose audio options (Dolby Digital 5.1, DTS 5.1), select Listen, then choose Y for the format you prefer.

Listen to Commentary
To listen to Christopher Nolan's audio commentary, select Comments, then choose D. The commentary contains four subtly different endings, each of which randomly branches off at I:33:52 time mark. One of these versions slows downs and starts running backwards, unintelligibly. The other three versions offer only subtle differences.

Choose Subtitle Options
To choose subtitle options, select Read, then choose Y for questions 3 or 4. On this page, you'll see a coded question that needs to be deciphered. The decoded question is The question is whose lies to you believe; yours or ours? Interestingly, the t in question is missing. A hidden feature may lurk here, but I've not yet uncovered it.

Disc 2 contains a bevy of supplemental features. Before I step you through the process of getting to them, here's a list of what you're in for:

1) Chronological Presentation: An illuminating re-edit of the film that allows for new appreciation for Memento's structure.
2) Anatomy of a Scene: A 25-minute full-frame documentary originally aired on the Sundance Channel.
3) Director's Script: Lets you view the entire annotated shooting script as the film plays.
4) Memento Mori: The original short story by Jonathan Nolan.
5) Theatrical Trailers: Contains the U.S. and international theatrical trailers.
6) Production Stills and Sketches Gallery
7) Props Gallery
8) International Poster Art Gallery
9) Concept Art Gallery
10) Bootleg Cover Art Gallery: Just two pieces of bootleg cover art.
11) Journal: Pages from Leonard's journal.
12) Menu of Supplements: Lists only the advertised supplements (Trailers, Anatomy of a Scene, Director's Script, Production Stills and Sketches gallery, International Art Campaigns).
13) DVD Credits

Disc 2 continues the psychological-testing theme of the first disc. The main menu displays 24 graphic icons, but only 6 of these icons get you into Disc 2's test-themed submenus: the Compass, the Clock, the Book, the Globe, the Skull, and the Binoculars. Here's how to access the above-mentioned supplemental features without experiencing a headache:

Chronological Presentation
To access the chronological re-edit, select the Clock, and choose C on the following five pages. You'll see a quiz that shows four illustrated panels of a woman changing a flat tire on her car. The quiz asks you to place the panels in chronological order. The trick, of course, is to place the panels in backwards order, which is 3, 4, 1, 2. After you do so, the film begins playing its scenes in chronological order. Playfully, this cut starts with the end credits rolling downwards. After that, the film's forward-moving black-and-white sequences begin, focusing mostly on the Sammy Jankis back story. (The chapters have simply been rearranged in chronological order.) This re-edit is presented in Dolby ProLogic. Although you can't fast-forward or skip forward through this presentation, you can jump to certain time codes.

Anatomy of a Scene Featurette
To access this featurette, select the Skull, and choose C on the following three pages. You use your angle button to switch from the film to the script.

Director's Script
To access the Director's Script, select the Book, then choose C on the following two pages. You can use your angle button to switch on-the-fly between the script and the film.

Memento Mori Short Story
To access Jonathan Nolan's original short story, select the Clock, then choose C on the following five pages. You're back at the quiz that shows four illustrated panels of a woman changing a flat tire on her car. This time, place the panels in chronological order, which is 2, 1, 4, 3.

To view the U.S. and international theatrical trailers, select the Binoculars, then choose C on the following five pages.

DVD Credits

In each stack, you'll find a page from which you can navigate left or right. You'll recognize this page because you can glimpse pages on either side of the centered page as it flips toward you. If you choose A on this special page, you move to the left; if you choose E, you move to the right.

Once you're rotating through this left-and-right navigation, you can access several screens from which you can access special features. The special-feature screens appear in the following order (in a loop):
