I've been trying to burn copies of my wedding onto DVD and haven't had much luck with this brand. Out of 25 discs, only about 7-8 burned successfully on my imac. The other ones gave me a failed burn message with either a medium write error or a disc failed to verify error. The TDK brand seems to work better for me but I guess it depends on your machine. It's a shame because it's a lot of money being wasted on experimenting with brands.
