Specs The NS-PDVD8 features an 8.5-inch swivel screen that can even fold down so you can view your videos tablet-style. It also comes with three headphone jacks, allowing everyone in your row to hear the movie on the plane. Oddly, however, the remote control (which always seem extraneous for a device that should never be more than an arm's length away) doesn't have a volume control.
Playback Expect about four hours of battery life out of the NS-PDVD8, enough for two standard movies (or one of The Lord of the Rings movies).
Showtime The NS-PDVD8 is good value for the price, and offers some flexibility with viewing options, but don't expect great sound, long battery life or amazing video quality - still, it's more than good enough for your kid's 108th viewing of Shrek 3, saving your notebook's battery for more business-related business.
Specs The DVP-FX930 comes with a high-resolution nine-inch screen and weighs more than 1.2 kilograms - pretty heavy for a portable DVD player. It also comes with a convenient car adapter, and ships with a remote control and AV cables.
Playback Sony's DVP-FX930 shines with a high-resolution LCD screen, two headphone jacks and up to six hours of battery life. It can also play MP3 audio files and display photos if they are burnt onto a CD or DVD.
Showtime You get what you pay for, and those who watch a lot of DVDs on the go will find the DVP-FX930 a sound investment.
Specs The DMP-B100 boasts the ability to play your Blu-ray discs on the road, though you may not fully appreciate all the medium has to offer on a portable 8.9-inch LCD screen. It also has a unique, mini-desktop design, and allows you to move the screen back and forth to get just the right non-glare angle. However, it has only one headphone jack.
Playback The DMP-B100 promises only a three-hour battery life and a feature-rich, though complicated remote control.
Showtime While the Blu-ray resolution leaves a lot to be desired, the DMP-B100 will provide a viewing experience a step above normal portable DVD players. But it's relatively short battery life means you won't get to enjoy the visual benefits for long.
