Some applications, as I understand it (and I'm not sure if iTunes falls into this category), do not actually receive the original bit-stream as read from the disc raw, which is the problem we talked about when trying to duplicate an audio disc, but re-sample the audio signal that was decoded by the sound card. So the disc is actually read and decoded, then re-digitized back to create the audio file. Not much is lost during this process, nothing that is perceivable at least, but it is not a bit-by-bit reproduction. dZ.
