I've recently bought a new Samsung DVD burner (SH-S162L / RSWN) and uses these blanks. The result was that the torch has burned them, but could not read (tested on other DVD drives: 1 of 5 drives the DVD could see). With DVD DL blanks from other manufacturers, it has, however - works! Straightaway - both writing and reading. In general, I am of the opinion that one should not skimp on the medium in securing important data. Since the burner actually read everything with which you feed him, I would advise against this precaution blanks.
