In qwakrz post, it doesn't merely say that 12x is the sweet spot for MCC 004, but that "Anything below 8x turns them into table coasters or bird repelent and 8x is only just acceptable".
IMHO I was being kind when stating that there must be something wrong with media or firmware, because I might just as well have said that qwakrz comment was pure disinformation, and qwakrz stated it very assertively which makes it even worse!
But I chose to believe that this was in fact what qwakrz experiences!
Since you (zebadee) want to defend this statement, are you then effectively agreeing that MCC 004 is not designed to be written slower than 12x, and if you burn it slower it will only be fit for table coasters or bird repellent? No? I didn't think so!
Even though we may have different setups, a slow system or external drive doesn't make it more difficult to get a good burn at slow speed, but it might make it more difficult to get a good burn at high speed. So that doesn't explain poor burns at slow speed. :disagree:
So the remaining explanations are: 1. I only get very good media and burners (not likely), or 2. qwakrz had some bad MCC 004 media, or 3. qwakrz's burner has firmware that is not designed properly for slow burns on this media.
