In addition to Polytropon's sage advice, I need to mention that you never 
said that these were rewritable DVDs you're working with. Not saying 
you're that dumb, but *I* am that dumb so it's the sort of thing I might 
have overlooked. Also, make sure that (assuming they are rewritable) they 
are the right kind for your drive: the "plus" and "minus" discs are not 
the same; that's DVD+RW versus DVD-RW.
