Hi TheBeart, I'm at work at the moment so I'll just give you the slightly shorter answers to each question
1) This used to be true, but as they were recieving too many conacts with problems, this isn't the case anymore...depends on how old your copy of Nero is.
2) Supported brands are an irritating issue and annouying. I'd suggest try this one first, as it's by far the easiest.
3) In regards to the firmware - this should always be your last option...we'll venture down this alley if we can't think of anythign else.
