New CD´s with errors, acording to dBpoweramp

Do you have any clues about this subject? I supposed that the new cd´s will be perfect while ripping...
Sometimes they have slightly weaker reflection. Try cleaning your laser lens.
Of course all CDs have errors: what you see are too many errors for the error correction process to handle. Examine the disc closely and you may see the problem. Sometimes a good cleaning will make the disc play.

Leog, I seem to be replying to a lot of your threads! I too have had this happen with brand new CDs. The CDs look fine but sometimes just polishing the CD lightly with a clean soft cloth will take care of the problem. Try to clean from inside to outside - never around the CD. Failing that, dBPoweramp has options for changing the way secure ripping occurs. Look under the ripping method section of the options menu. There's also a "defective by design" section that will try to handle CDs with "special" content. Sometimes these are enhanced CDs with video or other content but there have been some CDs produced that were encoded with information to make ripping more difficult.

The least desirable method would be the burst method (also selectable under ripping options). This just takes what the CD drive sends with no error recovery (other than what the drive provides). There may be glitches or dropouts with this method but the rip will still succeed. - Dick
A number of months back I posted on the measurement of C1 error rates on various audio CDs I tested with my Plextor DVD drive. They have a utility on a PC (PlexUtilities) that will scan any CD/DVD for errors.

I found a large variation in error rates. Some have argued that C1 errors do not effect CD playback, but that the more serious C2 ones will. I am not so sure. I very rarely found any C2 errors in all the disks I measured.

I found some recently pressed domestic pressings to have C1 errors in the few hundreds, while my Japanese SHM CDs had a total C1 error count under 10 on the whole disk!!!

I also found somewhat higher error rates on older 80's pressings, but some recent pressings were as high or higher than these as well.

Unless the disks were dirty (I always cleaned before measurement), polishing the surface had NO effect on the C1 error rates measured.

If you are ripping, I also found the higher the measurement speed, the higher the error rates on the same disk. As a result I measured error rates at the slowest speed the Plextor would run at. I suggest you rip at the slowest speed as well.
