i used to have no problems at all burning iso images and other files but suddenly i was having all sorts of troubles. i don't if the problem lies on the blank media or the burner itself or something else. i really have no clue what else to do. i've got a BenQ DW 1620 and recently updated the firmware to B7W9. here's the error log:
