3G file burns to -514M file on DVD-R

I have a gzip'd database backup file that's 3GB in size. I used mkisofs
to create an iso image for burning to a DVD-R. Both the mkisofs and
growisofs process appeared to finish successfully; but 'ls -alh' shows
the resulting file to be -514M in size when the DVD-R is mounted in
FreeBSD 4.10. When I mount the dvd in a separate FreeBSD 5.4 system,
ls -alh results in 'ls: /cdrom/pgdumpall.gz: Value too large to be
stored in data type'. I ftp'd the original 3GB file from the FreeBSD
4.10 system to the FreeBSD 5.4 system. ls -alh reads the size of the
original file correctly.
Windows reads the DVD-R and shows the file size correctly.
I've tried recreating the iso image using -r and -l options and burning
the iso file with and without the -dvd-compat option; but the results
remain the same.
Any ideas or advice?
