Cyberhome CH-LDV700B Portable DVD Player with 7-Inch Screen
Do Not Buy This!
From day one it never worked properly.  Would take several reboots to read a DVD.  Had terrible problems blacking out or going dead if the power cord was jiggled.  It was still under warranty, so we sent it back and the manufacturer sent us a new one.  Same problems with the new one.  Battery life is not long enough to play a movie all the way through.  Very cheaply made.  Don't waste your money on it.
