You don' t have to do manually that procedure :D (I'm talking about making standalone cds - no codec-player installation needed).
You can use HWmaker v2.0F instead, which supports BSplayer v0.8x and v1.00, Media Player Classic and the filters below:
Video: DivX, XviD, FFdshow, Matroska, Ogg Vorbis, RealMedia
Audio: Mp3, Ac3, Aac, Ogg
