Since they are copied discs (which means no copy protection), you CAN just ‘drag and drop’ the files. Having said that, there are better alternatives to doing it this way. I would suggest DVD Decrypter, simply copy the disc as a single .ISO image file, then burn that file with DVD Decrypter, ImgBurn, or Nero (or others). Also, with Nero you can just copy the disc, just don’t select ‘on the fly’ and it will temporarily copy the files to your Hard Drive as it creates a copy of the disc, then it will delete them after the completed burn. I prefer DVD Decrypter but the end result will be identical to the original regardless. With DVD Decrypter, select ‘Mode - ISO Read’ to copy the disc to the Hard Drive as an .ISO Image file, then ‘Mode - ISO Write’ to burn a copy.
