GOM Media Player

As various media players jockey for position to become your default setting for music and video streams, GOM Media Player's support for a wide range of file formats has helped it stand out as a firm favorite.
Supported formats include DAT, MPEG, DivX, XviD, WMV, ASF, AVI, and MOV, as are common codecs like FLV1, AC3, OGG, MP4, and H263. A pop-out playlist can save and organize your various media files, though the limited sort modes--two--hardly makes it a champ.
More impressive are the customizable settings on the control panel. Here you can adjust a video's image brightness, hue, and saturation. There's no preview window, and changes occur as the video runs, so unless you care for a rousing session of trial and error, be sure to tweak the settings after clicking "play." There's also a built-in screen-capture feature that includes zooming and panning, customizable themes, hot keys, and a host of preset and adjustable audio controls.
GOM is weakest when you're looking for help documentation and trying to tweak Save settings, but overall it's a very strong player worth at least a supporting role in your video-watching habits, if not the lead.
