[slinkelist] CDDB Lookup problems

[Stan Kurzet]

Looks like the erroneous duplicate problem is simmering again.

I believe that this is a class of problem that must be addressed by Colby.
Clearly, there is something going on with the CDDB algorithm and the fact
that different players produce different track and total times for the same
disk.  Worse, both of these factors appear to be beyond CDJ's control.   One
thing that may help is an understanding of what correction,  if any, can be
applied to particular players  to see if that will avoid the errors and/or
ambiguities.  Of course, if the problem lies in a defective CDDB algorithm
it could be that there is absolutely nothing that Colby can do about it.  As
I reported a month ago, I have disks where no two of the 12 tracks on each
has anywhere near the same track time, yet these are reported as duplicates.

COLBY:  It's time for you to jump into this.

One thing that may be a way out is this:  When CDJ extracts the disk ID per
the CDDB algorithm,  it should also generate a CDJ ID based on its own
algorithm.  Then, a disk will not be reported as a duplicate unless both
ID's are identical.  That may solve the problem, at least in those cases
where CDDB reports the data correctly when either one of the disks is
installed.

In the meantime, I am going to take one of my erroneously reported
duplicates, burn it to a blank and add silent track(s) to the copy to throw
off both the track count and total time.  I'll experiment to see what
minimal additions are necessary to force differentiation of the disks.
