max file size on cd9660 file system?

[Vivek Khera]

I was testing the interoperability of burning a DVD-R on my mac desktop 
with reading it on FreeBSD 5.2.1.  When I mount the DVD in FreeBSD, it 
gives me the following error listing the files:

[root at crash]# mount -t cd9660 /dev/acd0 /mnt
[root at crash]# ls -l /mnt
ls: mm.21-May-2004.dump: Value too large to be stored in data type
total 116002
-r-xr-xr-x  1 root  wheel        440 May 25 09:54 README.mm-dump.txt*
-r-xr-xr-x  1 root  wheel  118786146 May 21 03:03 rt2.21-May-2004.dump*
[root at crash]# df /mnt
Filesystem 1K-blocks    Used Avail Capacity  Mounted on
/dev/acd0    2374660 2374660     0   100%    /mnt
[root at crash]# umount /mnt


Sticking the disk onto my MacOS 10.3.3 box, it shows up like this:

% ls -l /Volumes/dd
total 4748296
-rw-r--r--  1 vivek  unknown         440 25 May 09:54 README.mm-dump.txt
-rw-r--r--  1 vivek  unknown  2312337081 21 May 03:59 
mm.21-May-2004.dump
-rw-r--r--  1 vivek  unknown   118786146 21 May 03:03 
rt2.21-May-2004.dump


The disk format is "HFS+" which is a superset of the Juliet extensions.

My guess is that the file size limit is 1Gb, given that when I look at 
other DVD movie files, they're always broken up at 1Gb file size per 
segment of the movie.  Can anyone confirm this?
