Magnavox MPD720 7-Inch Portable DVD Player
Great DVD player
We have had this DVD player for 4 months and have been very happy with it.  We bought it to get our kids (2 and 5 years old) through a long plane ride and it did the trick.  Since our plane ride was over 5 hours, we called Magnavox and ordered an extra battery (around $55 with shipping).  The player is sturdy and lightweight--perfect for travel.  We have since used the player a lot and have had no problems.  The picture is good and the sound is adequate for a portable player, and our experience is that the battery lasts for over 3 hours. If you are thinking of buying this to use on a plane, I would recommend bringing along a short bungee cord (available at Home Depot).  We had some bad turbulence for part of the flight and the bungee cord kept the player secured safely to the tray.
