- CSS: unlock scrambled-sector reads on enforcing drives via bus-auth
only; classify sense 6F/03 as CSS-locked; early-bail on a fully locked
scan; gate the AACS handshake off DVD discs.
- DVD first-play menu no longer prepended to the feature: read the title
VOBS base from vtstt_vobs (0xC4), not the menu VOBS vtsm_vobs (0xC0).
- Interlaced field-duration (DefaultDecodedFieldDuration) written as a
direct TrackEntry child rather than inside Video, so Windows reports
the correct frame rate.
- Audio channel count read from the AC-3 bitstream; FieldOrder set to
TFF; per-track BPS tags.
- Structured disc diagnostics at --log-level 3; reduced per-operation
log spam.
