OPlayer is actually a pretty darn useful app. In the interest of full disclosure: I've been using the iOS version for about a decade, and OPlayer is my default movie player in the iDevice side of things. That being saud, I only recently decided to try out the desktop version, primarilly due the poor reviews. Low and behold, the desktop version of OPlayer is slmost as good as the iOS version. Obviously, the desktop version is missing a few features that the iOS version has nativly, but it's still sold. In fact, I've used OPlayer to jimmy open video files that even the vaunted VLC can't (or won't) open. All that being said, I'm very happey with OPlayer. 9/10
