Audiovox D1710 7-Inch Slim Line Portable DVD Player
watch for the frozen screens...
I was given the audiovox as a gift and it is an impressive looking little unit.  It's really slim in size, and the screen size really is sufficient for getting the effects of any movie from Open Range with Kevin Costner to Matrix Revolution. The volume is not very loud, although it is fine if there is no other peripheral sound.  However, stick a pair of earphones on, and it's great.  But after several movies, I also began to experience frozen screens, black screens, and the select scenes icon would not activate. However, it doesn't happen on every film, and movies can be watched to the end, and enjoyed for the most part.  The bottom also gets quite hot during viewing.  As I received it as a gift, I certainly can't complain about the price, but I might recommend looking at other portable player reviews, and seeing if they highlight similar problems before buying.
