Coby TF-DVD7050 7-Inch TFT Portable Tablet-Style Portable DVD Player
great for little kids in the car...
this unit is compact and efficient.  the tablet form factor is great for mounting on a car headrest.  the speakers are just enough for a kid in the back seat, or it comes with two headsets.  for small kids it has a control lock out, so they cannot work the front buttons if you don't want them to.  it does not have a/v in. the batt allows viewing a two hour movie.
