Member who just replied to you, made those extension for most audio type (as part of his project IIRC)
You also need to remove .ogg from the directshow list (where the directshow codec was setup, not on that exclusion page) and install the native ogg decoder for dbpoweramp.
/ add your extensions on new lines, ie .rm.mp4v.m4v.vob.tta.rmvb.ra.on2.rm.ogv.ogm.mts.mpc.mqv.mov.mka.m2p.k3g.ifo.hdmov.flv.evo.alac.mkv.divx.axv.axa.spx.ac3.tak.dts
>[HKEY_CLASSES_ROOT\ogmfile\DefaultIcon]>@="C:\\Program Files (x86)\\Haali\\MatroskaSplitter\\splitter.ax"It is possibly this which is taking preference over dbpoweramp, try renaming 'DefaultIcon' key (folder) to 'DefaultIconxxxx' then restart your windows.
Tak support would require us to fully support the codec (decode and potentially encode).
