Note that you might want to try out #9 of the pre-2.0 series. There were still some problems in the generic read handling when errors occurred, and I hope those are finally fixed (knock wood - the code is certainly not trivial, and I haven't been able to test). Pre-#9 also contains the SCSI fixes from Leonard, so people who have seen problems with SCSI cd's, could you please check this out and see if we have them more-or-less nailed now?
