CYBERHOME CH-LDV 700B 7-Inch Widescreen Portable DVD Player
What a headache!
This product has been one headache after another.  First, the monitor didn't work at all.  After I exchanged it, the new DVD player had a battery that didn't work.  When I tried to contact CyberHome about the problem, I didn't get a response.  Do yourself a favor and get a different DVD player.
