Maplin are pretty good for quality and price from past experience.
This is how I see it, a dvd player is a dvd player, if you want fancy features you pay more, this does DivX which is how I play my movies to save the DVD, quality will be reduced to fit several on one DVD, as it's in the car and only 7" you can't expect home cinema quality.
So all round good
(Basically I'm trying to get opinions as I really want a DivX player for house and car, I already use a portable DVD player between house and car!)
