Cyberhome CH-LDV700B Portable DVD Player with 7-Inch Screen
Battery Life is not good
I bought two of these for both of my children to use.  They would put in a movie and before the movie was over the screen would start to flicker and then it went completely black.  The sound is good and the picture is clear but the battery is an issue.  I would never take this on an airplane cause it might only get you through take off before it quits on you.
