These are the most-reported symptoms, and I have also seen them yesterday. > Usually a second try actually does write the data, even after a machine > reset. Correct. I did some quick tests yesterday and it looks that it works every time if the DVD+R medium is inside the drive when it is powered up. It behaves as if the drive does not fully recognize the medium - which is strange, because it correctly reports its type. > It's as if the flag for a simulated write had been accidentally set within > the software, but not in the window icons. DVD+R does not support simulation mode (something that is...erm... not especially well-reflected in CDVDBurn's dialogues) anyway, so this can't be the problem.

This drive, while I don't own it myself, can be considered "supported". I think the symptoms we see are not drive specific. Steffen
