That's interesting. I found a different sample, and ffmpeg indeed isn't capable of "reducing" it. I was in doubt whether 96/24 was an extension, but at least Wikipedia confirms: "DTS 96/24 is implemented as a core DTS stream plus an extension containing the deltas to enable 96/24 sound reproduction." I'm not sure that means that the extensions need to be there, or whether they are optional. If there are extensions in there, there seems to be a shortcoming in ffmpeg's dca_core bitstream filter. BTW, if you use ffmpeg's decoder (and thereby re-encode, of course), it does have the option: -core_only <boolean> .D..A.... Decode core only without extensions (default false) I haven't checked whether that works though...
