I found this nice review of blank DVD media and thought it might be helpful

Of course we all know that we only burn copies of our favorite movies when
we own the movie and want to have a backup. ;-)

I always had good luck with Sony and TDK. Being the tightwad I am, I wait
to buy a supply till they are on sale.
