Coby TF-DVD7100 Portable DVD Player
Great little player!
Love this DVD player.  The picture quality is great.  The sound is great too but have never used it in a car or airplane so cannot comment on that.  At home, though, it's plenty loud enough and would guess that if you got some noise cancelling headphones they would do the job just fine.  It's much higher quality than I expected for the price range.
