MPlayer Portable

MPlayer Portable is a media player that can be carried around on any USB flash drive, without the need of installing it on a computer and without leaving any files behind.
Just like the full version of the app, MPlayer Portable is a very handy application whenever you want to play a video file, as long as it uses any of the following formats: AVI, ASF, WMV, MOV, MP4, RealMedia, OGG, FILM, RoQ, PVA or NUT.
Of course, there's the same plain-looking yet very familiar interface that allows you to take full advantage of the great features hidden under the hood, so you won't get in trouble when using MPlayer Portable.
As for the features, the same great player we know. It opens a video file in a second, it provides an excellent audio and video quality, and lets you change a bunch of settings such as audio track, subtitle track, aspect ratio and deinterlace.
There's an options menu as well that enables you to pick the sound output driver, the DirectSound output device, aspect ratio and language, but you can also decide whether to run with higher priority and to rebuild file index is necessary.
Since it's portable, you won't have to install the app. It's enough to copy the whole application on an USB flash drive and that's basically it, you can always launch it using the provided executable file. It's very light, as it barely exceeds 7 MB of space, so it won't take too much space on your portable storage device.
Although we agree that MPlayer Portable is a great app with powerful tools and a nice interface, there are some minor issues that we discovered during our test. For example, the main window doesn't show the video duration, so you will have to hit the 'Clip Information' button at the bottom of the screen.
Other than that, MPlayer Portable remains a top product and since it's so light and comes with so many great tools, we strongly recommend you to give it a try.
