Review comments at @dvd/dvd_dump.ixx:
- Line 838: Update the optional Jamless Play disable request using
is_jamless_play_firmware and drive_set_jamless_play so transport exceptions are
caught at this best-effort boundary and do not prevent the dump from continuing
to READ CAPACITY. Preserve the existing warning when the request returns
failure.
