I just received the big five-HD-DVD box set today of everything "Matrix," the set known as "The Ultimate Matrix Collection." It looks to contain all the materials found on the previous "Ultimate" ten-disc SD set. The first three HD-DVDs include the feature films, the "In-Movie Experiences," and various standard-definition extras; and the final two discs, "The Matrix Experience," include the "Animatrix" series of short films and sundry other items on double-sided discs.
However, for a moment I had to wonder if Warner Bros. hadn't overreached themselves. Although the 1080 picture and Dolby TrueHD sound on the first disc I watched were exemplary, I ran into a minor fluke switching to TrueHD. Once I made the change, I used the "menu" button on the remote to return to the movie. Wrong. I couldn't get the pop-up menu off the screen; indeed, while the movie continued running fine, I could no longer use any of the buttons on my remote. I had to shut the machine off by unplugging it. Plugging it back in put things back in order, and I had no further trouble. In fact, try as I might, I could not duplicate the error. I suspect it was a once-only glitch, a bug in the matrix, perhaps, or a speck of dust that got in the way of the laser. We'll see.
