Yes, hence why DVD-RAM support in Linux was almost since day 1.

Some drives you can, but yes, they are limited to Masushita/Panasonic
data drive licenses. A lot of that has to do with the advanced error
correction and MO design, things that are _not_ in CD-RW, DVD-RW and DVD
+RW. The error rates are much lower in comparison, hence why I still
recommend DVD-RAM.
FYI, +R/+RW compatibility wasn't very good until recently, especially on
consumer players. Yes, better than -RAM, but -RAM was designed for
optical archiving and longevity, and it does it well. People forget
that +R/+RW/-RW do _not_ physically look like -ROM/-R at all, so there
are compatibility issues as well.
And yes, -R is the ultimately compatible format when written in Disc-At-
Once (DaO) mode, which requires byte-by-byte (character) record. And
since DVD-R(G) came out, I adopted it as well. But for prior archiving,
as well as some archiving since, DVD-RAM gets the call.
I avoid DVD+RW/-RW like I did CD-RW (and CAV/zone-CLV CD-RW, or what I
retroactively call CD+RW). The error rates are too high. DVD+R isn't
like DVD-R either, so I avoid it, especially with the fact that it
wasn't until late 2003 that even Sony/Philips players/licenses weren't
always DVD+R compatible.

It is mathematically impossible for someone who makes more than you
to be anything but richer than you. Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them). Linear algebra, let alone differential calculus or even ele-
mentary concepts of limits, is mutually exclusive with US journalism.
So forget even attempting to explain how tax cuts work. ;->
