GOM Player includes many codecs (XviD, DivX, FLV1, AC3, OGG, MP4, H263 and more) so you wont need to install separate codecs for most videos. For those videos that require a separate codec, GOM Player will find one and direct you to a place where you can download an open source version of the codec. That way, you wont get stuck with unnecessary codecs on your system.
