Mintek MDP-1770KIT 7-Inch Portable DVD Player Kit
Problems right out of the box
I received this DVD player as a Christmas gift.  The picture is great, but the first time I used the player I had problems with the movie freezing and the DVD player not responding - I tried it with multiple brand-new DVD's and always got the same result.  After a couple of weeks I became so frustrated that I returned the player and exchanged it for a Toshiba SD-P1400, which is a few bucks more but also comes with plenty of extras - Hopefully it will turn out to be more reliable.
