The problem is that libdvdread is compiled with large file support
(CFLAGS = -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64)
and your program is not so off_t/size_t and so on may have different sizes.

You also use the size values in the dvd_stat_t as int when they infact
are off_t.

Your get_size() function returns an int but the size of buf.size is off_t.

Set your CFLAGS to largefile support as above.
Handle the sizes as off_t not int (off_t is probably 64 bit when compiled for
largefile).
Change your treestore to support off_t or use some type that can handle 64bit
gint64 perhaps.
And change your printfs to print 64bit numbers instead of 32 (%ld -> %lld
depending on your platform).
Now everything should work.

Hope this helps.
