What is an OGM file?
Compressed video file that uses an altered form of Xiph.Org's Ogg file container format; supports playback of video content that incorporates DirectShow filters; created as an extension to the Ogg specification so that Windows Media Player (older versions) and other programs could easily play Ogg video and audio files.
NOTE: Xiph.Org, the owner and developer of the Ogg specification, does not support the OGM format because it lies outside of the Ogg specification. The OGM format is different than the format used for .OGG and .OGV files.
