It is however important that filters are properly registered with the Filter Mapper. For the developers…
Another example of a negligence with a cost of incompatibility and enormous amount of support time. Ahead Nero installs a number of DirectShow filters into $(Program Files)\Common Files\Ahead\DSFilter directory. One of the files is NeResize.ax and it hosts a Nero Resize filter. Let us take a closer look: CLSID: {30002E0C-C574-481E-A5DE-90AE54A79E10} (note that Nero 8 ships…
