I have a problem backing up classical music CDs with my new DVR-112D using both Nero and CloneCD. I am getting lots of popping type noises on the copies. Looking at the audio waveform with Adobe Audition I can see minute gaps (about 0.01 seconds) in the waveform where these popping noises occur. I obtained a replacement drive from my supplier but this has not cured the problem. If I use older drives (DVR-108, DVR-106 and an old Plextor) I get perfect copies.
If I use Adobe Audition to extract the audio from the CD to wav files and burn the wav files back to CD using Adobe Audition I get a perfect copy.
I tried downloading the latest versions of Nero and CloneCD but neither of those cured the problem.
As far as I can see there is no problem writing or copying DVDs.
