If you're after a portable DVD player to keep the kids entertained on long car trips, you'll appreciate Shinco MDP-1770's clear image, support for most common media formats, and nifty extra features.

The Voxson SL-77 offers quality DVD playback on the road, but a lack of support for compressed formats like DivX and XviD limits its appeal for power users.

Though it doesn't include support for MPEG-4-based video formats, Voxson's entry-level SL-50 offers a clear, bright screen with Dolby Surround support. And you can even plug in an external input.

The DVD-ZK7 offers some high end features like progressive scan NTSC and PAL playback, but it's let down by poor stability and a lack of DivX video support.

The PET710 suffers from a lack of image and sound quality, although the car seat holder and the car charger adapter are handy for car travel.

An integrated LCD screen and DVD player, the Sony DVD Station is a cool little appliance, ready for you to watch movies when you're on the road.

Some clever design features like dual headphone outputs and swivel screen make up for a lack of volume from the in-built speakers and some minor contrast issues.
