A CD with copy protection can normally be identified by the corresponding IFPI copy protection logo. It’s a black circle with a white triangle. You can find it here: https://de.wikipedia.org/wiki/Kopierschutz A tip: It is recommended to read a CD first with a program like iTunes and import it to your computer. Then the transfer to hörbert’s memory card is even faster. ITunes also has a good converter that brings the tracks into the optimal format (m4a or better still mp3). This is similarly convenient under Windows with the Media Player, but you have to set the mp3 format there, because the hörbert software does not read files with the extension.wma. After importing into iTunes, you can drag and drop songs directly from the iTunes library to the corresponding playlist window in the hörbert software using the hörbert software.
