a) Check cdrecord options for a 'quiet' mode, where only the bare
minimum is printed.  Never used it myself, but ^H^H^H^H sounds like an
updating bar graphic designed to display progress.  You don't need it.

b) expand your external system call to include a pipe into a filter.

c) did someone suggest CL-PPCRE (same as 'b actually)?

I've done something similar with NGREP, but I also hacked it's source
code to get what I wanted.  CDRECORD might be clean enough for you to
do that too.
