Reading large ISO 9660 file systems (over 4GB) results in a file that has ISO header at the beginning of file, and a copy of it right after (2^32 - 1)th byte.
You need to be careful when reading ISO 9660 file systems from DVDs.If the file system is larger than 4GB, libiso9660 can't handle it properly. One of library functions (iso9660_iso_seek_read()?) uses byte offset parameter, and that offset is wrapped back to zero when it reaches 2^32 bytes.
