I mounted the DVD in question; here's a directory listing. So it seems 
that there's some trickery going on. A random diff'ing shows that these 
are different files or they result in an I/O error.

selene:/media/dvd/VIDEO_TS# diff VTS_09_1.VOB VTS_10_4.VOB
Binární soubory VTS_09_1.VOB a VTS_10_4.VOB jsou různé <= different
selene:/media/dvd/VIDEO_TS# diff VTS_09_1.VOB VTS_10_1.VOB
diff: VTS_09_1.VOB: Chyba vstupu/výstupu <= I/O Error
selene:/media/dvd/VIDEO_TS#

selene:/media/dvd/VIDEO_TS# ls -alh | grep 0G
