I thought there was a “sticky” place where to post recording results, but I missed it. Sorry for the inconvenience, if any
I’ve spent a lot of time, and money, discovering that every media works fine with some writers and very bad with some others.
At present I can tell you that a 40125S with firmware ZS0N works very good with:
Verbatim CD-R 40X 700MB Extra Protection Surface
ATIP: 97m 26s 66f
702.83MB (79m 59s 74f)
I always record it at 32X with no error at all.
Some (recoverable) errors might appear when recording at 40X.
I’m investigating some Philips and some Sony too. Will post the results as soon as they are ready
I hope to be of use for somebody
