Mintek MDP-1770 7-Inch Portable DVD Player
Mine works like a dream...
Honestly.  I have had absolutely no problems with my Mintek. I've had it for 7 months. I've used it a lot too, as I travel frequently and even have used it for a month (almost every night)connected to my big TV when my regular DVD player at home went out.  Picture is clear, and the system is convenient with good sound.  I think that the other reviewer must have just gotten a defective player...?
