Any portable DVD players use AA batteries?

[Sukhoi]

I'm going to be taking an eight hour flight this summer and I'd like to buy a portable DVD player. I have a lot of rechargeable AA batteries and will be bringing the charger anyway, so I'd prefer a portable DVD player that takes AA batteries. But are there any? I went to HHGregg, Best Buy, and Circuit City yesterday and every player they had took Li-ion batteries.

I guess my other questio is, are there any Li-ion players that have easily replaceable batteries if I buy a second pack? The ones at the stores appeared to be screwed in.

Thanks!
