I'm using growisofs and DVD+R media, running growisofs against a tree of
links to an nfs volume.

I guess that would be a good thing to try. I have been trying to avoid
making the image beforehand because it increases the amount of time
required, and haven't been burning as root because the files are on an
nfs mount that squashes root, I guess I'll give both of those ideas a
try and see what happens. Thanks for the suggestion.
