Samsung DVD-L70 7-Inch Portable DVD Player
Nice DVD player for the price
I bought this for my daughter for Christmas and she watches it quite often.  The picture is nice.  The sound is OK.  It plays many different types of discs and so far she has had no problem playing any DVDs.  She has not taken on any trips so I don't know how it does with a lot of movement.  The battery lasts about 3 hours which is not bad.
