I've had chance to check out a couple of portable DVD players : the Yamada PVD-500 (£130) and PVD-700 (£170). The players are similar in many respects. They both come with a detachable battery and all the leads you need (if a bit short) to hook up the video and sound out to a TV or home cinema system. For in-car use there is also a lighter adapter and small pair of headphones. The built-in speakers are very tinny so the headphones are recommended. Both players come with the same power adapter which you can plug into the player or the battery. Both players have the same thin remote control. The 500 is a solid little unit and you'd rely on the remote for most operation including the screen contrast/brightness/sharpness/saturation settings. IT has a 5 inch 4:3 screen which is fine for portable viewing. The NTSC/PAL switch on the back of both players is a boon for people with cheap TVs which don't do NTSC. And the initial inspection using the composite output looks very impressive. The other outputs are S-Video (lead supplied), composite and coaxial (yes picture & sound) doubled on one socket (lead supplied), stereo audio (cable supplied) and headphones (supplied).
