nope, but apart from indentation problems the code is fairly modular
and the atapi stuff is all confined in the new files
cdd_atapisomething.[ch]

the port is for 3.0 and not cam-ified. I have a port for 2.2 as well if
you need it (it is not committed yet)

i do, if that is the problem.

this is what i did -- upgrade from an old SONY 2x to a samsung 32x
which works very well. The problem is, ATAPI drives are not as good as
SCSI ones, especially 2-3yrs old models, even brand name ones e.g.
Sony.  Plus, in many cases people do not have the option to upgrade,
e.g. in the case of laptops.

no problem, it was just a suggestion. jitter correction is the main
(and possibly only) reason i prefer cdd over all other audio grabbing
utilities :(
