<div>DirectShow Filters usually have to be COM-registered on the PC in order to use them for playback. But the registration is only required when you want the filter to be found automatically. If the application handling playback has some very specific filter that will only work directly with it, you can also use the filter file directly. This method is escpecially usefull when the user's registry is broken or has invalid entries for filters. We can directly control which file is loaded - the file that was deployed with our application.</div><div>MediaPortal has a few filters that we can load using this method. (e.g. MPUrlSourceFilter, IPTVFilter, MPAudioRenderer).</div>
