You're welcome, ric.
I'm glad that your burns seem to be testing satisfactorily for errors now.
You have plenty of fans, as I do.
Reinstalling the same ASPI drivers should not have any effect on burn quality. Running a newer version of KProbe (or cooler temperature) may possibly have had some effect on error reporting.
Buffer underrun protection is only one feature of Liteon's Smartburn. I also know that this works with RecordNow Max as I have run the same dual burning experiments and seen the drives recover from interruptions. Smartburn has four features, and it is the last three to which I was referring. See SMART-BURN
1. Buffer Under Run Error Free
2. Running Optimum Power Calibration
3. Automatic Writing Strategy & Burning Parameters
4. Automatically decrease burning speed when Laser power over margin due to poor media quality or high temperature
If RecordNow Max has only three undefined speeds of Min - Mid - Max, I question whether Smartburn is being adequately supported.
You may know that Nero 184.108.40.206 has a "Relax Joliet restrictions" feature which is supposed to "Allow more than 64 characters for Joliet names". Naturally, it doesn't say anywhere how many more characters than 64 are allowed.
NTI programs like NTI CD&DVD Maker have been able to burn long filenames of up to 128 characters for years using the Romeo format.
