If the playlist files are high-resolution, they may exceed the 650 MB capacity of a CD-R even though the total playing time of the playlist is less than the 72 minutes of a standard CD. In addition, CD24 discs are ISO9660 discs that incorporate better error correction than a standard Red Book audio disc. The error correction data takes up some space on the disc, so what fits on a Red Book CD may not fit onto a CD24. Please check the Owner’s Manual for a comparison of Red Book vs. CD24 disc capacities.

In cases where the CD24 image is larger than 650 MB, you'll need to create two new playlists and "distribute" songs from the original playlist evenly onto the two new ones (so that each is smaller than 650 MB). You can still keep the original playlist, but use the two "splits" to perform the CD24 archive.
