One of the hottest apps in the iPhone/iPod Touch scene lately is video player that supports other video formats not supported by the built-in video player of said devices. The video formats that can now be played with the use of these video players are divX, Xvid, mkb and mpeg. VLC is a free app that not only supports Xvid but also plays mkb and mpeg. VLC, being free, has bugs though such as crappy video playing especially when the file being downloaded is big in size and has high quality. It also does not have a lock screen option which is annoying. On the other hand, CineXplayer is a paid app that can play divX and Xvid formats. Although CineXplayer is limited when it comes to supported video formats, it has better performance and has a lock screen option and zoom-in feature that make watching videos much better.
