I had a number of discs, maybe 20 out of 1500, where dBpa did the "re-rip frames" thing as well. A frame on a CD is a chunk of data that has a computed error checking code associated with it (IIRC, 75 frames/second of music). If dBpa reads a frame, and its computed error code doesn't match the one on the disc, it will keep re-reading the frame until it comes out right.

Sometimes, the frame reading issues were fixed by cleaning my discs. Other times, though, the errors were specific to the drive I was using to rip the disc. My Memorex drive would tend to exhibit these errors on the last track of very full CDs (like 75 minutes or so). I could often cancel the rip of that track, rip it from my LG DVD-ROM drive instead, and it would not need to re-rip frames, or at least far fewer. The LG, on the other hand, would sometimes have issues on the first track.

What's interesting about this is, most ripping software would never even figure out that such read errors had occurred.
