Macgo Free Media Player is - you guessed it - a free media player for Windows and Mac.
The program can play DVDs, local audio and video files, and various URL types: HTTP, FTP, RTSP, MMS and more.
Installation is easy, with no adware or other hassles. (The developer is hoping you'll upgrade to the $59.95 Blu-ray supporting version, so doesn't want to annoy you in any way.)
The program appears to be based on VLC Media Player, which means you can be sure of quality playback for every disc and file type.
What Macgo Free Media Player tries to do is reorganise and simplify VLC's endless options and settings to make them easier to find and use. If you need to adjust your picture, for instance, there's no pile of tabs to explore, no confusing jargon: just click Window > Adjustments and drag sliders to tweak brightness, contrast, saturation, gamma or hue.
The program has various extras, too - like posting comments to Facebook or Twitter directly from the player window - and it's all packaged in an attractive and straightforward interface.
