Good C1 and C2 error values



since i can’t search for it, because c1 and c2 are too short words, i just ask here:
what are good max/avg values for c1 and c2 errors when doing a quality scan of a CD with nero cd-dvd speed utility?
and what speed is recommended for CD scanning?



i know this link is for kprobe and you use cd speed but i`am sure the results can be simularly interpritated.
