The ID number comes from the last 6 characters of the volume serial number. For
example, one of my CDs[1] shows up in cdplayer.ini with ID number D1E113. Going
to a DOS prompt and doing a dir on it gave the following:

F:\DRR>dir l:
 Volume in drive L is Audio CD
 Volume Serial Number is 00D1-E113

 Directory of L:\
01/01/95  12:00a        <DIR>          .
01/01/95  12:00a        <DIR>          ..
01/01/95  12:00a                    44 Track01.cda
01/01/95  12:05a                    44 Track02.cda
and so on.

The ID is stored on the CD as the last 6 bytes of it's serial number.

Hope this is Useful Information (tm).

"Oh dear. What a pity. Never mind."

[1]: The CD was _Kansas_ "The Best of Kansas", just in    case anyone was
wondering. Now, what should I listen to next: Journey, Metallica, R.E.M., or
Yanni?
