Cyberhome CH-LDV700B Portable DVD Player with 7-Inch Screen
Cheaply Made
I was looking for a cheap portable DVD player that the kids could carelessly handle without real worries so I purchased the Cyberhome 700B.  Right out of the box, the unit seems a little flimsy to me.  The included options are pretty extensive which is why I'd give this unit 3 stars.  The biggest issue, besides the battery problem that others have mentioned, is that when a DVD is placed in the unit, it begins to spin and it makes a strange noise.  I figured out that the disk is off balance and the unit will not read the disk until it's balanced.  I do this by tilting the unit slightly.  It becomes quiet and then reads the disk.  This is a minor problem.  The picture is quite good when you raise the saturation and contrast levels.  Probably would look elsewhere if I was buying again.
