OK, I got it, you meant this:
Let's ask Pioneer about it. I'll come back with more details.
Yes! Thank you for posting a picture -- that really helps. Your picture is typical of the graphs I get with factory pressed audio CDs. Sometimes my graphs are actually much more even -- i.e. the dips are VERY evenly spaced and the size of the dips is quite consistant, growing slightly over the length of the graph. A lot of the time, however, my graphs look just like that one. Once in a LONG while I'll actually get a graph with no bumps, but a second scan of the same disc will once again have the results shown above. Once again, this only happens with audio CDs, not with data CDs or DVDs.
Your test also confirms that the newest drive (the 110) still has this issue, making the effected drive models the 07, 08, 09, AND 10.
I'd be VERY interested to hear what you find out from Pioneer.
Thanks for helping out with this,
