It's Thursday evening -- do you know what that means? Besides being the unofficial start of the weekend (party people, what's up?), it's time for another round of Ask Engadget. This week we've got a college freshman who's scared to death about 8-hour flights between his hometown and his new school... without gadgets.

"I'm about to start college all the way across the country from my hometown. What this means for me, other than unprecedented freedom, adulthood, etc. [and a dose of this thing called the "real world," might we add] is lots of long flights back and forth. I'm looking for a device to entertain me during these trips. Is there anything out there that the readers can find that can play DVDs (ideally from any region, but that's not a deal-breaker) along with my AVI files and maybe some audio formats, too? The biggest issue here is battery life. I'm willing to spend $300 - $400 if I have to. Any help would be greatly appreciated. Cheers!"

We're not so sure there's a portable DVD player / PMP hybrid out there that's extra longevous, but you can always get those discs onto a vanilla PMP with a little work. So, jet-setters -- what's the best solution here? Video playback really takes a toll on handheld battery life, but are there any hidden gems that just keep going and going? Hook a brother up, and then send in a question of your own to ask at engadget dawt com.
