As a suggestion to tracking down the "failure mode".  If the ISO CDs
are burned using the command line cdrecord...were they burned with
or without the "padsize=33" option?

If without, maybe someone who is having the failure could use
the same hardware but try burning the same ISO file with
cdrecord with the option "padsize=33" (and without the option "-pad").

I have seen speculation that the problem is due to the dma overrunning
the end of the ISO and not recovering from the "error" correctly.
Adding that much pad might then bypass the occurrence of the error.

WARNING:  This is ONLY SPECULATION
