DVD titles play the way their navigation packs say: interleaved cells
as their own units, chapter names from the VMG, region mask, IFO stream
labels, a whole-title forced-subtitle probe, DvdPs-only stages. UHD
keeps mastering metadata and hdr_plus_flag and fixes dvcC. HD DVD
decrypts AACS per pack by each EVOBU's CPI and joins PEVOB features;
Class II MKBs are reported.
Fixes and tests from the second audit across bdnav, labels, ifo, codec
parameter sets, mkv/mp4/stdio, css, aacs, keysource, keys, decrypt and
sector code. An HD DVD copy already in the clear needs no key, with one
encryption decision for every AACS format; image and folder titles are
named by the meta title, else the playlist, as in 1.7.7.
libfreemkv::spec holds the verbatim specification quotes the code
cites, with guards tying each governed site to its quote. A test-util
feature exposes shared fixtures to downstream tests. M2TS output
derives DTS for reordered video and rounds to whole 90 kHz ticks.
