Among the crowded marketplace of free audio-video players, GOM Player offers a user interface that sets it apart from the competition. Like the similar Korean KMPlayer, GOM Player offers a simplistic UI that both casual and advanced media users can navigate easily. In addition, GOM Player's compact size uses very little RAM, so it's ideal for users who own less-than-optimal computers. GOM Player supports almost every audio and video file imaginable, including the popular QT and RealMedia formats. Furthermore, if GOM Player doesn't offer the necessary codec, it automatically searches for it online.

However, Linux and Mac OS X users must search for an alternative media player since GOM Player only runs on Windows operating systems. In addition to its complete file support, GOM Player offers a variety of advanced features, such as A-B repeat, key remapping and video effects. Screen capture and playback speed control are also available, allowing the user to do more than just watch videos. Because GOM Player supports MOV and FLV files, there's no need for a separate QuickTime or an FLV media player installation. Speaking of installation, a handy setup wizard walks the user through the install process, and it configures the playback settings based on the user's needs.

Depending on the user's computer, GOM Player offers three modes: Normal, High-Quality and TV Output. Normal mode works with most Windows computers, including systems with less memory. High-Quality mode optimizes video playback, but it uses more system resources. TV Output mode works best for home theater systems, and its 5.1-channel audio mode offers quality surround sound for music and videos. As with any free media player, the GOM Player includes an array of features for both audio and video enthusiasts. It works on low and high-end computers, and the sleek design makes it a joy to use.
