A four-way keypad located on the MVP's front panel allows intuitive navigation of menu levels, file lists, and other features. An Escape button takes you back to the previous device mode, while the Menu button accesses various features, including playlists, the six available EQ presets (there's no user-programmable EQ), repeat one/all, and shuffle. A rocker switch on the left side of the device lets you zoom still images and adjust the volume.
Among the MVP's main-menu options are music, picture, and video icons that you select to drill down into the respective categories. In terms of interface design, the MVP's only significant drawback is that it doesn't filter by ID3 tags. As a result, you have to navigate music using the filenames and the directories under which files are stored on the unit. In other words, you can't browse music by categories such as artist, album, and genre. You can, however, arrange the music folders to your liking.
The MVP's connectivity includes a high-speed USB 2.0 port, a power-adapter jack, and three multiformat memory-card slots. Minijack video and audio outputs allow you to play the unit through your home-theater system, for instance. A minijack audio input for line-in recording rounds out the MVP's connectivity. The unit also has a built-in microphone for voice recording.
In the box, Wolverine includes a small, basic remote control with 10 blister-type buttons. Although you're unlikely to use the remote for portable applications, it's good to have if you connect the MVP to your home-theater system. The company also supplies a black hard-shell carrying case with a built-in speaker that's powered by two AAAs.Supported audio-file formats include MP3, unprotected WMA, unprotected AAC, and WAV. The Wolverine Data MVP also supports M3U playlists transferred from your computer and has an add-to-queue-type on-the-go playlist function. The absence of support for DRM-protected files will put off Internet-music-service users. In the video realm, the MVP plays MPEG-1 files at 352x288-pixel resolution and 30 frames per second (fps), as well as MPEG-4 and DivX 5.x/6.x files at either 720x480-pixel resolution and 25fps or 640x480-pixel resolution and 30fps. Unfortunately, MPEG-2 and WMV files aren't supported.
Given its large hard drive, multitude of card slots, and decent LCD, the MVP makes a good tool for storing and viewing digital photos. It can display JPEG, TIFF, and BMP image files as well as raw files from certain digital cameras. Although this feature is not listed in the specifications, the device is also able to display a nonanimated GIF file. You can configure the MVP to automatically stretch images to fill its entire display. It can zoom still images up to 4X and rotate them. Viewing a photo slide show with musical accompaniment required a few more configuration steps than we would have liked, but it was nonetheless a fairly quick and painless process.
