I always use CDDAE99 which can be set to do a double pass the second being compared with the first, this gives a good assessment of the CD quality, Green = All Ok Yellow=some errors Red=definately bad.. Funnily enough though even the RED tracks sound mostly OK.
CDDAE99 is really critical, and reports every single bit error, so don't be too worried as long as 95% is OK sound doesn't seem to suffer..
Sorry I don't have a link to the site on this PC but the name
errik.deppe@pandora.be was the authors original email
and
http://come.to/cdspeed was a site dealing in otherr CD test facilities some while back, I notice also that the latest NERO has included a re-badged version of the CDSPEED in its utilites folder.
Snark..
