ok, i tried another burn with the stock 812 formware (unpatched), and it is a coaster, and from the DVD view, it seems failed the first upshift.
update:
at the end of the log (not pasted here) nero checks 2 registry keys, alocated CDroms, and vcool. does vcool make things bad? (vcool to make AMD/via computers cooler)?
but the question remains, the computer is the same in all cases with +RW and +R, why does it fail +R? it’s firmware things…
here is log:
