The American Film Institute's #10 film of all time makes its glorious debut on Blu-ray. Warner has done a marvelous restoration job, as UAV Editor Scott Wilkinson explains in this report. Here, I'll highlight a couple of jaw-dropping scenes that illustrate how this work translates to the finished project. The Dolby TrueHD 5.1 audio track won't shake the foundation, but given its age, it sounds remarkably good, especially when Judy Garland belts out a tune.

The head of Disney Animation, John Lasseter, once said, "From the beginning, I kept saying it's not the technology that's going to entertain audiences, it's the story. When you go and see a really great live-action film, you don't walk out and say 'that new Panavision camera was staggering; it made the film so good.' The computer is a tool, and it's in the service of the story."

I didn't connect with this HBO original series based on the books by Charlaine Harris, but the DTS-HD Master Audio 5.1 soundtrack is to die for. The score features a full-bodied sound, the dynamic range is impressive, and the creative sound design utilizes every speaker in the room. Quiet passages reveal crickets chirping, and dialog is never strained. The video is solid, but I'm focusing on the audio for this Ultimate Demo.

And now, Ultimate Demos are new and improved, with icons that let you instantly see which titles have exemplary video, audio, or both. If the stylized eye is red, you know that disc provides exceptional visual imagery, while a red ear icon indicates outstanding sound. If either icon is orange, the corresponding content is very good, but not quite up to reference quality, while a gray icon means there's nothing special about that part of the presentation.

Keep in mind that Ultimate Demos are not movie reviews—they will always provide top-quality audio and/or video, even if the movie itself doesn't measure up to the disc's technical merits. So if you've been looking for Blu-rays that kick some serious home-theater butt, look no farther than HT's Ultimate Demos.

After filming Superman Returns with HD cameras, director Bryan Singer used 35mm film in the loosely based true story Valkyrie, in which Colonel Claus von Stauffenberg (Tom Cruise) attempts to assassinate Adolf Hitler. The film opens in North Africa with a rich golden hue; when Stauffenberg ventures back to the fatherland, the color palette opens up with bold reds and lush greens. Although the film is a middling affair, the audio and video presentation is stupendous and a demo showpiece.

While the special effects are well done, the over-the-top action gets a bit tiresome after nearly two hours. The video encode is serviceable with adequate depth and detail, but it's the DTS-HD MA 5.1 soundtrack that is the star of the show. It features very intense bass, a plethora of discrete effects, and reference-quality dynamics.
