It may be that the cd9660 filesystem cannot correctly represent files
over 2gb, so mkisofs skips files larger than that.  Mkisofs explicitly
rejects files over 2^31 bytes:

tree.c:1520
    if (S_ISREG(lstatbuf.st_mode) && (lstatbuf.st_size >= (off_t)0x7FFFFFFF)) { 
        errno = EFBIG;
        errmsg("File %s is too large - ignoring\n", whole_path);
