Hmm burned about 5 coasters today trying to figure this out, all Verbatim 16X DVD+R burned on my Samsung SH-203B (SB01 and SB03) @ AUTO Write Speed. I used these same discs in the past with the same burner without problems before I upgraded to Vista.
I noticed there once was a Potential 'WaitImmediateIO' Deferred Error which passed on the second try.
I had an ImgBurn.ini in the program folder which I cleared because I figured certain XP settings may have persisted.
My user account has 'User' rights but I have successfully burned other discs without being 'Administrator' on Vista.
I usually burn at half the advertised rate.
I am using AHCI.
I wanted to post about this before burning more coasters.
[EDIT] I also got the exact same error below with a different DVD+RW disc.
