Unfortunately Infiniti sucks at media playback. I spent so much time trying to convert movies and shows for my kids into a format specifically for playback in the car via USB. It was crappy at best. So I've given up and we just use DVDs. Frankly if your biggest thing is the entertainment for the kiddos - I would consider something else. The Durango for example, has large TVs at better viewing angle (behind seat rests, not on head rests) and they play Blu-rays and multimedia a lot better. Disappointing for us who want to stay with Infiniti.
