Audiovox D1700 Portable DVD Player
1680 is much better
I originally purchased this model instead of the Audiovox 1680 because I prefer the widescreen setup.  However, this unit was nothing but trouble.  It is flimsy and was unable to play several newly purchased DVDs. Further, the method for recharging the battery was really unintuitive and clumsy.  I returned it in favor of the 1680.  The 1680 is very solid (and heavy) and despite the fact that it has a more traditional television width ratio, I have been very happy with the unit both as a portable and as a home DVD player.
