This is probably too late to help you ric, but the disks are plastic,
and the actual media that the recording is made into is a layer in the
middle.  The plastic can be buffed.  I had a favorite dvd movie that I
loved, and it got scratched.  I used toothpaste (not a gel, the old
paste), and a soft cloth (a diaper which we keep for working on varnish
and my motorcycle windshields) and buffed it out.  Take a small daub of
toothpaste, and using a circular motion with the finger(s), just keep
polishing the area with the scratch out to about 0.5" from it.  This
will restore the clarity of the plastic and the recording can be
rinse, buff and repeat until the scratch is no longer present when light
is reflected off the disk.  Make a copy once it is working, because new
drives spin quite fast and I suspect the disk physical integrity may be

Hope this hint helps some of you with those disks you thought were lost.
