The contributions from experienced users are valuable to help eliminate problems, but I notice there is an immediate jumping on users' posted logs showing an I/O mode of "PIO Mode". However, I have an indication that DVDFab (7.0.9.0) may not always detect this mode correctly, and may show "PIO" when "UDMA 5" is actually in use.
With two Optiarc AD-7241S drives in place, my DVDFab_burn_VSO.log shows:
