In my experience this seems to be the fault of the drive.

Trying to mount a UDF formatted DVD-RAM disk for writing with
a Plextor-750 will force a read-only mount.  I then have to issue
a remount:

mount -t udf -o remount,rw,noatime ...

Now I can write to the disk.

But using the same disk with a LG GSA-4167B drive, this behavior
does not occur.  I can mount the disk for writing directly:

mount -t udf -o rw,noatime ...

With this LG drive there is no need to issue a remount.

Also, using the Plextor I experience other problems with DVD-RAM
and UDF which are absent with the LG.

Unfortunately, the logs show no informative messages of any kind
and I have no way of debugging this further.

I would suggest that, if possible, you try a different DVD drive
and report back here.
