FordMan, although you showed the differences between burns on 1.05 and 1.06, but nobody knows whether plextor changed the writing strategies for that particular media @4x or not. Furthermore, if we rely on plextor's changelog, the 1.06 doesnt say anything about writing strategies and writing quality.

- Improved the performance and write strategies of AutoStrategy with both DVD-R and DVD +R media.
- Improved the writing performance and quality on DVD+R, DVD-R, DVD+R DL and DVD-R DL.
- Improved the disc mounting performance with DVD-R DL media.Improved the performance of PoweRec so that the user may not override any media write strategy setting assigned by PoweRec.
- Fixed a bug where a DVD+R disc which may have additional date added, is recognized as a DVD-ROM and will not be able to write to it.
- Added support for new DVD+R, DVD-R, DVD+R DL and DVD-R DL media.Added support to write at 6X on some DVD media if supported by PoweRec.
while 1.06 changelog
Date posted: April 1, 2005
- Fixed a bug introduced in 1.05 firmware which could result in a write error while burning on some brands of DVD+/-RW media.
- Fixed a bug introduced in 1.05 firmware in which a user could not disable PoweRec and select any specific write speed in Roxio Creator applications.
My point is, like others have said, its mainly due to many things:
- media variations, not all disk-- even from the same spindle, is the same.
- system interactions, how your pc, software, burner and media interacts at each burn.
- environmental condition, such as temperature, humidity etc.
