I bought this toy about 6 months ago. It worked great in the car on road trips, to keep the kids happy. Over the next few months, more and more movies quit working (locked up, skipped, etc.) The same movies still played fine at home on the set-top unit. After reading more reviews, this seems to be a common "feature". Needless to say, I returned it and bought a 9" TV/DVD combo that would run on AC or DC. All of the "defective" movies play without a hitch. This one is no where near as small or as cool but it works so that makes the kids and me happy.
