What about just extracting the files AAC_PARSER.AX FLVSPLITTER.AX MADFLAC.AX MATROSKASPLITTER.AX MP4SPLITTER.AX MPEGSPLITTER.AX VSFILTER.DLL and using a batch or reg file to install them. Thats a lot of installing if you install all those one by one. What are the actual files, I need to extract from these 3 files, I rather not have a bunch of extra files just the filters/codecs? 3ivx_d4_451_win.exe ffdshow_rev1936_20080413_clsid.exe oggcodecs_0.73.1936.exe Also I would like to add a few more codecs I use, can I add these to my directshow folder you suggested instead of the C:\Windows\system folder/ CLVSD.AX DIVXDEC.AX XVID.AX DIVX.DLL XVIDCORE.DLL XVIDVFW.DLL
