Portable DVD players? Any experiences?
Extensive experience.
They are quite handy and are extremely hardy, compared to what one might suspect. We had a couple with our unit while outside Falujia and in Baghdad. They have a really short battery life, though- like one movie... and not a real long one either.
I believe that the mostr popular was the cheeapest, made by Apex. They were reliable enough, though they would freeze up someand would scratch disks if too much grit was allowed to collect inside the machine; though they were less expensive to get broken if something happened.
Im sure that the bigger names will make better products.
