Movie Player

Movie Player is a free application which can be used to play lots of video and audio files. The program is similar to every known media player.

It plays your files, supports subtitles, and you can watch your video files in a minimized window or in full screen.
Adding files to be watched or listened to is very easy. Just click on the Open button at the bottom of the program's graphical interface, browse the file you want to add and it's done. After that, just hit the Play button and use all the commands as you would use them in any regular media player.
With Movie Player you can change the aspect ratio of your video files by simply clicking on a button.
You can add as many files as you want to the program's playlist, organize them as you want, and then save them in a playlist file so that you can watch the same files in the future without having to open each one again. The playlist can be hidden if you don't click on the 'show playlist's item.
The program comes with predefined hotkeys so that you can easily use the player. For example, by pressing the P letter, you can play the file or pause it; by pressing ALT + Enter the full screen mode will be enabled, and so on.
