Are these datasafe discs ok for burning dvd-video? Im thinking about buying some of these discs because of the price and also because they are sold in 10s. Has anyone had any problems with them? (im using a pioneer 105 to burn) The discs Im talking about are found here... http://www.blankdiscshop.co.uk/acatalog/FOR_DVD_R_RW_CLICK_HERE.html (dvd329 on website) Also could someone tell me if overprints are safe to buy. I saw some on the above website (dvd390)for a very tasty price.
