This is a superb piece of equipment, I've had it a couple of months now. I bought it mainly for viewing videos on long journeys and it does the job very well. The screen is clear and crisp, colours true and no blurring on fast action scenes. Sound is excellent. It can play just about any video format and it has had no problem with any video I have loaded onto it. Battery life is good. The menu system is intuitive and it is easy to zoom in or out as necessary. It automatically senses the aspect ratio of your videos, but if you have any that are too tall and thin or too short and fat, then you can just manually change the aspect ratio.
I love it.
