Hi Rob
I don't know whether it would be possible to burn a dvd from Pluto saved image, but I remember a post where those images were described basically like iso images so there are some chances.
If dvd is not heavily damaged you may give it a try with dvdisaster (
www.dvdisaster.com). I never used it but i've read that it's a good tool and it's open source.
It can also help you to create a crc image file that consistently increase the possibility to fully recover a damaged dvd. This may not be your case (you have to create crc image before dvd gets damaged), but probably it's worth a try.
