This is thwe latest important change incdda2wav and it allows to use a value
that would need a second run if you like to do things manually: paraopts=proof
means use overlap that is maxtransfer - 1 sector.

Did you also tell cdda2wav to use speed=1?
If you cannot repeat this now, it would be impossible to find the reason now.

Temparature influences results.

I fixed some bugs in cdparanoia (e.g. a buffer overflow problem and some
problems in the code that creates the statistics).
These problems most likely still exist in cdparanoia.
Also note that cdparanoia uses the kernel interface to read audio data. This
results in fewer reported errors and in worse data in some cases.
The kernel uses simpler code and does not evaluate all error information that
is checked by cdda2wav.
The error report written by cdda2wav is a result of many tests with bad CDs
that include listening to the results.
