Thank you very much for your fast reply (faster than the Swiss Post...). I'll give the Verbatim-DL and the cleaning recommendation a try, before trying a new drive. Firmware already checked. best regards from Switzerland

Perhaps the Verbatim-Recommendation does match also my problem. Anyway I'll post my Log. Perhaps it is another self made issue. I try to burn an image on a DL DVD. The process stopps and has made already some discs useless. On the same discs of Memorex I burnt the same image already with success. Many thanks for the help! classicrange I 21:22:36 Operation Started!
