- can remove DTS zero padding and repair outdated DTS-ES headers
- can apply positive or negative audio delays
- can reduce bitdepth of decoded audio data by using TPDF dithering
- can resample decoded audio data (using SSRC or r8brain)
- can apply/reverse PAL speedup on decoded audio data (SSRC/r8brain)
- can demux video / audio tracks of EVO/VOB/(M2)TS and MKV sources
- can list available titles of Blu-Ray and HD DVD discs
- can extract Blu-Ray and HD DVD chapter information and subtitles

-448               use e.g. "192", "448" or "640" kbps for AC3 encoding
-768               use "768" or "1536" kbps for DTS encoding
-core              extract the DTS core of a DTS-HD track
+/-100ms           apply a positive or negative audio delay
+/-3dB             apply a positive or negative audio gain (volume change)
-0,1,2,3,4,5       remap the channels to the specified order
-edit=0:00:00,0ms  loops or removes audio data at the specified runtime
-silence/-loop     forces usage of silence (or looping) for audio edits
-down6             downmix 7 or 8 channels to 6 channels
-down2             downmix multi channel audio to stereo (Dolby Pro Logic II)
-phaseShift        shift phase (when doing stereo downmixing, see "down2")
-mixlfe            mix LFE in (when doing stereo downmixing, see "down2")
-down16            downconvert decoded audio data to 14..23 bit
-slowdown          convert 25.000 and 24.000 content to 23.976 fps
-speedup           convert 23.976 and 24.000 content to 25.000 fps
-23.976/...        define source fps to be "23.976", "24.000", "25.000", ...
-changeTo24.000    change source fps to "23.976", "24.000", "25.000", ...

-stripPulldown     strips the pulldown from MPEG2 video tracks
-keepPulldown      disable removal of pulldown for MPEG2, h264 and VC-1 tracks
-seekToIFrames     make all h264/AVC "I" frames seekable
-check             checks if the source EVO/(M2)TS file is clean.
-test              checks if the external filters are installed & working
