- MkvTrack::audio emits A_DTS/MA, A_DTS/HR, A_DTS per the DTS family instead of mislabelling everything as A_DTS. Plex transcoder and strict hardware decoders reject DTS-HD MA payload under a plain A_DTS track. - PgsParser is now stateful: pairs display PCS with the following empty PCS to compute a duration. Frame::duration_ns + PesFrame::duration_ns carry it through; MkvMuxer::write_frame gains a final Option<u64> parameter that emits BlockGroup + BlockDuration when set. Fixes subtitle bitmaps lingering past their intended end-time.
