To doublecheck that:

%growisofs -dvd-compat -R -J -iso-level 3 -Z /dev/cd1 /path/to/data/*

And it is working. The "-iso-level 3" is required to burn DVD with
per-file-size >4GB, that is some large audio or video file.
Then I have created an ISO file form these files, to test the iso
burning, but I got this error:
growisofs: no mkisofs options are permitted with =, aborting...

So I suppose this switch is only aplicable at creating the iso image
stage. When a valid iso image is already created (ie. with "-iso-level
3" switch) no additional switch is necessary for growisofs. Please
note that I am already using the cdrtools-devel package (in cdrtools I
did not have this warning). Also old version of mkisofs  did not
complain about -iso-level 3 switch but gave an error that some large
files will not fit on image.

To confirm the image burning from an iso containing the large files
with no -iso-level 3 switch:

%mkisofs -R -J -iso-level 3 -o ../dvd.iso *

And after checking - the files are on the disk (the large file is
automatically split into two and works well).


Therefore I would recommend something like this:

Note:
If you need to burn directly to a disk or create an ISO file
containing files larger than 4.38 GB, the "-iso-level 3" option must
be passed to mkisofs(8).  Therefore this option has to be added to any
mkisofs(8) commandline while creating the ISO image, or growisofs(1)
command line used for burning directly to a disk, e.g.:

%mkisofs -R -J -iso-level 3 -o ../dvd.iso *
%growisofs -dvd-compat -R -J -iso-level 3 -Z /dev/cd0 /path/to/data/*

When you have an ISO image containing large files already inside, no
additional options are required for growisofs(1) to burn the image on
a disk.

Also, be sure that you have cdrtools version  >2.01, as the older ones
does not contain large file support. This propagates issues in other
GUI-based applications. Currently only the sysutils/cdrtools-devel
port contains alpha version fresh enough to support large files, so if
you experience troubles please move to the development package.
