Have had before. They all worked. No bad discs. Work great when used in computer. Will not record on DVD recorder /player. Have DVD/VHS recorder and player and DVD recorder player different brands. Will not record on DVD+RDL. Big block comes up can not record on this disc. Put same disc in computer did perfect job. The double layer (they say) give better picture. A lot of the movies are on DL. Some like 007 ( I was told longer than two hours) and to get better picture than standard DVD is why it is used. Standard DVD is 4.7 GB and DL 8.5 so to me that seems right. ### There is nothing on the top no right writing- nothing. . You can burn what you want. OUT FREAKING STANDING. deserves many stars more that 5. At one time I could not get all Verbatin in pack to work. I ordered 20 and about 10 did not work. I took a chance on them over year ago. Glad I did. Worked great. Would buy again. Wait I did. Would recommend to friend.
