These two directories and their contents are not being listed yet via FTP:
./pool/main/libd/libdvdcss
./pool/main/v/vapoursynth-deblock-dmo
The commands I use to reproduce the behaviour are:
$ lftp ftp://deb-multimedia.org/pool/main/libd/ <<<ls | grep libdvdcss
# subdirectory libdvdcss not listed
$ lftp ftp://deb-multimedia.org/pool/main/libd/libdvdcss/ <<<ls
# can cd to it but lists no contents
$ lftp ftp://deb-multimedia.org/pool/main/libd/libdvdcss/ <<<"get
libdvdcss_1.4.0-dmo2.dsc" # can get contents know the names
$ lftp ftp://deb-multimedia.org/pool/main/v/ <<<ls | grep
vapoursynth-deblock-dmo # subdirectory vapoursynth-deblock-dmo not
listed
$ lftp ftp://deb-multimedia.org/pool/main/v/vapoursynth-deblock-dmo/
<<<ls # can cd to it but lists no contents
$ lftp ftp://deb-multimedia.org/pool/main/v/vapoursynth-deblock-dmo/
<<<"get vapoursynth-deblock-dmo_6-dmo1.dsc" # can get contents know
the names
