Thank you for reply.

I found that it can be mounted correctly by mount_udf as follow.

freebsd# mount_udf -C UTF-8 /dev/cd0 /cdrom
freebsd# ls -l /cdrom/test
total 5242880
-r--r--r--  1 root  wheel  5368709120 Aug 17 16:58 test5g

I'm verified that 33gb movie file on BD-R DL is accessable correctly.
