I have Ubuntu Precise 12.04, with udisks 1.0.4-5ubuntu2.1.

This version contains the patch that sets mount option 'dmode=0500' for UDF discs.

However this patch does not work for DVD-RW that are not finalized (However I don't know if finalization makes a difference).

Not finalizing DVD-RW is handy because it allows to burn e.g. several TV broadcasts on the same DVD-RW in several times. In my case I have a Sony DVD recorder, and apparently this recorder does not set correctly the directory permissions. Because of this, and because the patch above does not apply, I cannot read the DVD-RW on my ubuntu pc.

I looked at several ways to overcome this issue. First there is apparently no way to override the default mount options in udisks. At least, this is not clearly documented. My only resort then was to patch the udisks package directly. I join in attachment a patch on udisks 1.0.4-5ubuntu2.1. Basically the patch forces 'dmode=0500' for all optical discs with UDF filesystem.
