Panasonic DVD-LX9 9-Inch Portable DVD Player
The best there is!
I wanted to buy my wife a portable DVD player and reviewed several models to include &quot;hands-on&quot; demos and the quality of the Panasonic easily beats them all.  The number one feature to consider, of course, is picture quality and the LA-9 mimics a HD picture --truly amazing for such a small unit.  The LA-9 is pricy but well worth the cost.  We often take plane trips lasting 3-5 hours so it got even pricier as we also bought the optional battery pack for longer play and sound cancelling earphones.  The cradle is a big plus as we use it to play DVDs through our kitchen TV.  All in all, a VERY flexible unit with features galore for either travel or at-home use.  If you can afford it, this is the one to get.
