Hi together, as already written above, I would like to ask you about your experience regarding CD blanks. Have a BlaupunktLos Angeles MP72 and have problems with my CDs. Both the CD-R 80 (Aldi-Ware) and the CD-RW 80 will not be played. In the manual, CDs will be written with a 74 minute playing time. Furthermore, the format of the CD should be in ISO 9660 Level 1 or Level 2 or Joliet. I don’t know what that is. Can you give me tips on which CDs I should take? without buying up the entire CD stock from the media market?
