AFAIK (AIANAE ;-) there is nothing specific in the driver to deal with
jitter and doesn't really need to be.  Dumping the tracks uses digital
audio extraction.  Absence of jitter is a design feature of most
drives that support digital audio extraction (http://www.cdrfaq.org/faq02.html#S2-15).

FWIW, I've not found differences (using cmp) between consecutive
rippings of the same track...I've done a significant fraction of my CD
collection with this method and been very happy with the results
(thanks Soren!)

Kind Regards
