It is not supported on newer FreeBSD either, I think. Looking at the files in
/usr/src/sys/fs/udf leads me to believe that there is no writing support.
There doesn't seem to be a fusefs port for it either. But have a look at
sysutils/udfclient, that might help.

Personally I've always used dvd+rw-tools to prepare an UDF image.
And since HDDs in USB enclosures became affordable, I haven't used DVDs
anymore. They're just too small these days. Trying to back up a >100 GiB
harddisk to DVDs gets old pretty fast.
