Unfortunately, I cant say I can mimic your results.
I went so far as to uninstall nero everything, and even wiped the registry of ahead and nero entries, and re-tried, and it worked, tried it 4 or 5 times, then rebooted cause i was recovering a HD and installing a new one, and after that I tried today, and again, a coaster was made. Then I went looking in the registry, and in there I noticed under the yamaha there was a subkey with a reg entry for autowritespeed, which none of the 3 other burners had, removed the entry, and it works again, but unsure if that key will return, or even if its going to work. But I dont think this is an isolated incident.
If that was the case Boskin, then explain why 5.5xx works with no trouble, but 6.0 doesnt, and yet all other recording software I have works flawlessly? (Not attacking, but curious).
I really think there is some issue, cause like I said, if 5.5 works right til the last build, why not 6.0?
And I have tried various media as well, so its not specific to one kind of media or brand.
