The standard that defines the format of an audio CDs is referred to as the "redbook" standard (I think because the original standard was published with a red cover). Therefore, the Redbook.sys driver is named after the CD standard. There are other CD standards that cover Data CDs, VCDs, SVCDs, ...etc also referred to by the color of the standard's cover. I know that VCDs are covered by the "Whitebook" standard and I think Data CDs are covered by the "Yellowbook" standard. Most of these standards were originally written by Phillips Corp. That is why Phillips was recently upset about copy protected audio CDs carrying the "digital audio CD seal" (you know the symbol on the CD) when the discs do not and cannot follow the "Redbook" standard. I hope this helps explain the name.
Regarding the message:
"This drive has not been shown to support digital audio playback."
Not all CDROM drives are capable of digital audio playback (usually requires a different type of sound cable between the drive and your sound card to carry digital rather than analog data). Digital playback is more precise but is more difficult to accomplish. Analog sound output is the norm for CDROM drives.
