Philips PET710 7-Inch Widescreen Portable DVD Player
Kid friendly, and great for trips!!
With the dual headphone jacks, and the bright picture, this is an excellent portable player to take in the car, on the plane or to have in the hotel room.  It is easy to pack, fits in most medium sized camera bags, and is very easy to use.  Both our 4 and 5 year old use its features without our help.  Great product.
