Nero 7 is very bloated in size and gimmickry .. and it's audio encoding of cd's has
had some issues which may not have been resolved, but which worked fine in Nero 6.x
As to Vista, Nero 6 may not work, so if you are going to Vista or a 64 bit os, then you
may have to use Nero 7 or maybe something like Roxio Media Creator (latest version)
which is not too bad. There are other programs out there that can do CD / DVD burning
some less expensive, some very easy to use.
