No, unless you're using DL media, the capacity of the DVD is approximately
4 gb. And you aren't finding any 16x DL discs yet, as far as I know.
Your dvd+rw-mediainfo run below supports the fact that you only have 4gb
discs.

Pick one. The documentation for growisofs makes it plain from the examples
that you can either specify the directory containing the files to burn
(since it will call mkisofs as needed) or create an ISO yourself and burn
that.

Typically, +RW media needs to be formatted, also as documented. Usually,
+R and -R do not.

Don't know what you need other than growisofs's man page.
