It looks like FW 1.06 ist a improvement for Sony DVD -R 16x (Sony16D1). All results are from a TLA#0202 drive with PR and AS on.
First a little history:
With FW 1.04 PR would kick in at 3.2 GB. The burn was slowed to 12x. Never mind the slowndown, the resulting burn was good or even very good. The result can be seen here:
The fourth picture is a Beta/Jitter scan of a burn with FW 1.05. As the Jitter-graph shows PR kicked in at 3.3 GB. The burn was slowed to 4x! The result was a coaster. The drive reports a read error at this position. Side note: A burn with FW 1.05 at a speed of 12x resulted in a burn with no slowdown and a very good result.
Pictures 1, 2 and 3 are Sum8, Sum1 and Beta/Jitter scans of a burn with FW 1.06 (PR on AS on). This time, the media was burned in a clean 6.7-16x CAV with no slowdown. In comparison to FW 1.04, notice the disappearance of the "U-turn" in the Beta-graph at 3.6 GB.
Edit: TA-Test: Very Good; Good; Good
This is of course only a single media that has been checked. But it sure looks if the strategy for Sony DVD -R 16x has been perfected. So what of Zevias question if PR ist still too sensitive? I guess the answer ist "not anymore for some media".
Further testing will reveal more. Meanwhile i'm eagerly awaiting the changelog for 1.06.
