Reinstall winblows - because you did fatal mistake - instaling first programs and then soundcard - then the programs cant use it.
Partial solution - ninstall and reinstall only programs.
Similar example - you install windows, then install WinDVD and then install DirectX.
Result - WinDVD filters never ever work into other that WinDVD application, and there is no way how you can make it work.
Why - because W/O DirectX, there is simply no way that PlayDVD or similar util, like great DVDsubber can use filters - W/O DirectX. And the filters never ever use DirectX, because a time of install, there has not any DirectX, so, the filters dont have clue - so - all is lost and you have reinstall winblows.
Solution - none known, except possible registering the filters as DirectX filters nanually - if you are skilled and brave enought...
