I just downloaded Moboplayer today so I haven't had a lot of experience with it yet, but it seems really good. I like the easy controls for adjusting the backlight and volume without having to pause. Most of my videos are in Quicktime format and relatively short as I like to create time lapse movies from series of photos taken with my Canon dSLR. I did read a review that said Moboplayer doesn't remember where you left off on a paused movie if you close the app, so that would be problematic if you are watching a 2 hour movie. But maybe they can fix that before long.
