What is GOM Media Player?
GOM Media Player is freeware video playback software developed by the South Korean company, Gretech Corp. Designed with both power and simplicity in mind, GOM Media Player is an ideal video player for both beginners and experts alike.
Aside from being the most widely used video player in South Korea, the non-Korean versions of GOM Media Player enjoy a monthly worldwide user base of over 43 million in over 200 countries, making it one of the world’s most popular video players.
GOM Media Player includes built-in support for all the most popular video formats (MP4, AVI, WMV, MKV, MOV, FLV, etc), loads of advanced features (screen capture, audio capture, video playback speed control, and more), and the Codec Finder service that helps you locate missing codecs for formats that aren’t supported by default. You can even watch broken and incomplete AVI files with GOM Media Player.

>> Installation
Once the download completes, locate and launch the installer client.

The installer client should be located in your browser’s default download directory. To launch the installer, simply double-click the icon.
After you launch the installer, the GOM Media Player Setup window will appear.

This window is just a welcome screen. Click [Next >] to continue to the next step.

This window displays the GOM Media Player End User License Agreement (EULA). Please make sure to read this agreement carefully before you install the software.
After you’ve read the EULA, click the [ I Agree ] button to continue to the next step.

This window lets you choose which components you want to install, and allows you to set certain options such as file associations.
For most users it is recommended that you don’t make any changes on this window.
When you’re ready to move to the next step, click the [Next >] button.

If you’d like to change the installation directory, you can do so from this window. For most users we recommend leaving the installation directory as is.
When you’re ready, click the [Install] button to begin installing GOM Media Player.

The installation should take only a few moments. When completed, this confirmation window will appear. Click the [Finish] button to close the GOM Media Player installer.
** During the installation you may be presented with information and/or offers for other software products. It is entirely up to the user whether or not to accept / install additional software or services offered during the GOM Media Player installation process.
>> Configuration Wizard
The Configuration Wizard is a software tool that makes it easy to change the basic settings for GOM Media Player. The first time you launch GOM Media Player, the Configuration Wizard will pop up automatically.

The first window of the Configuration Wizard allows you to choose your display mode. “Normal Mode” is recommended for most users, while “High-Quality Mode” is designed for high-performance computers and displays. If you plan to use GOM Media Player for TV Output, select “TV Output Mode” for optimal results.
After you choose a display mode, click the [Next >] button to continue.

This window lets you choose basic codec and speaker settings.
GOM’s built-in codecs are designed to improve quality while consuming fewer system resources. If you aren’t familiar with manually configuring video and audio codecs, it’s highly recommended that you leave these two boxes checked.
For speaker settings, choose the option that best represents the speaker setup your computer uses.
To continue, click [Next >]

This window lets you choose which file types to associate with GOM Media Player (i.e. what kind of files will open with GOM Media Player automatically when you click them). On this screen all the video types are divided into groups to make it easier to understand which formats relate to which type of media. If you plan to use GOM Media Player as your default media player, we recommend leaving all of these boxes checked. Keep in mind that you can adjust your file association settings at any time after this initial setup (Changing file associations is explained in more detail
here).

This window lets you set the default subtitle display size and GOM Media Player’s process priority.
Regardless of which option you select here, precise adjustments to subtitle font size can be made at any time from the GOM Media Player preferences window (Subtitle preferences are explained in more detail
here).
Process priority refers to the amount of system resources your computer allocates to GOM Media Player in relation to other system tasks. Setting priority to “High” will maximize the amount of resources your computer will allocate to running GOM Media Player to make sure your videos play as smoothly as possible. However, because GOM Media Player doesn’t require much processing power to function properly, it’s usually unnecessary to set the process priority to “High” unless you’re using a low-performance computer.

Click the [Finish] to close the Configuration Wizard and launch GOM Media Player (if you don’t want to launch GOM Media Player immediately, uncheck the box before you click [Finish])
Remember that the Configuration Wizard can be run again at any time after this initial setup, and can be accessed via GOM Media Player’s start menu folder (the application is called “GOM Wizard” in this folder), or from the Preferences window of GOM Media Player itself (push the [F5] button on your keyboard to open the Preferences window, then click the [Reset] bottom at the bottom left corner and choose “Start Configuration Wizard”).
