how to get ogm files to work

when ever i load up any ogm files it says that they are unknown file formats. how do i fix this? or can anyone recomend a player that can play ogm files.

bsplayer can handle ogm files, provided you have an ogg splitter installed(a splitter is needed whatever the player, whatever the file type)

you can download tobias' ogg directshow filter (oggDS) which contains such a splitter and a Vorbis decoder
