If you are upgrading from the fre version to the pro version and want to keep your library you should go to Preference - Advanced and backup your library. Then you just select restore in the pro version.
mVideoPlayer is what I would say the best video player replacement application available for Android, with a lot of useful and handy features and a nice and clean interface it greatly improves on Android's built-in video player.
This app DOES ONLY PLAY WHAT YOUR PHONE ALREADY SUPPORTS so if you were looking for anything else, don't waste your time. It could however be used as a video library browser because it allows you to open videos with other applications. You can even select which application you want to use by default in preferences.
