I guess very few people need Vorbis in ffdshow. In fact only AAC, (E-)AC3 and DTS decoders need to be patched. Everything else either work as it should or simply not used. BTW I don't know who needs 12 (twelve) software deinterlacers (and +1 HW) in ffdshow.

I've read that paper. DTS encoder clearly works in frequency domain. To be exact, it operates in joint time-frequency domain, for every given time-window it decomposes input signal into frequency sub-bands and then works with that decomposition.
