Hi

The ISOCD9660 standard limits the maximum size of any individual file to 2G=
B.=20
You can split the file into smaller chunks (which you can reassemble) if yo=
u=20
wish to write an ISO compatible disc.=20

However, if you wish to eliminate the restriction entirely, you must write =
the=20
DVD as an UDF filesystem (ISO/UDF bridge). FreeBSD can quite happily mount=
=20
UDF discs (though some older DVD-ROM drives might struggle to read them=20
correctly).=20

As regards userspace tools, there is plenty of high quality burning softwar=
e=20
for FreeBSD that allows you to create UDF discs (i.e. K3b).

A "mkudffs" tool could be handy though.

Aren.
