I want to buy a portable DVD player for long plane rides (I currently live in Africa and travel to the US a couple times a year). I have a laptop, but the battery only lasts for about 1 movie. Here's the criteria I'm looking for: 1. long-lasting battery (2-3 movies would be good). 2. not too expensive ($100-200 range, hopefully) 3. not too heavy (less than my 6-lb laptop computer) Anyone have a suggestion for a model that meets those specs? Of course, good picture quality, and build-quality are always nice. Speakers are not important to me, as I would always use headphones. I know one of my problems is that I want long battery-life and light-weight. Maybe a model that uses standard size, replaceable batteries (such as AA) so I could replace them, even if it means several sets of rechargeables. But hopefully not a proprietary size that costs $100 or more for a spare.
