Hi, I'm flying from Australia to the USA and would like to purchase a portable DVD player. What's the best one to get that:

1. Has a long battery life?
2. Is USB compatible
3. Is avi compatible

Would I be better to get a rechargable battery one, or one with AC adapter?

Any advice would be great!

I don't want to purchase a lap top as I'm on a tight budget and don't need one at the moment
Thanks for your suggestion, I'l look in to it! Are you sure its avi compatible?

I'm flying with united airlines and I've heard some of their flights don't guarantee you an imbuilt seat monitor.. Just a cabin movie screen. I just don't want to be bored! Lol
