AFAIK - DL media (Double Layer or Dual Layer) does not come in a re-writable
format.
Which would mean there *is no formatting/erasing possible* of a DL DVD.

I could be incorrect and you have found some media (DL DVDs) someplace that
is re-writable...
Please tell us where and whom is selling it - although my bet is that it is
quite expensive if it exists.

The discs have an RW logo on them, so I assumed they are eraseable/
reformattable/re-writeable, just like the 4.7 Gb versions. I bought
two brands of these. Verbatim and Windata at Microcenter.

I feel silly asking this one: why do the discs have an RW logo on
them? That means re-writeable, correct?

Because they can't be erased, does that also mean that any files that
were put on that disc cannot be overwritten with new files if space is
needed?

Dual Layer DVD+R DL RW discs cannot be erased.Their format does not permit this at least for now.

I don't know of any re-writable Dual Layer discs, at least not at this point
in time... If the disks were to be re-writable, the disc would have to be
labeled "DVD+RW DL". I'm not sure what the RW stands for that you are
referring to, but even my Single layer write-once (DVD+R) discs have that
small "RW" symbol... That symbol does not indicate that the disc is
re-writable... Sorry...

Yes, I noticed the RW logo on the packaging of some DVD+R discs I purchased
a while ago, but I knew they weren't re-writeable, and it made me wonder why
it was there.

I'm not surprised someone was confused/mislead by it.

See how they use the symbols - seems totally contradictory to me.

I can't seem to find any info on exactly what the logo is meant to be
referring to - is it the recorder if not the disc or what?

I'm not about to buy and dual layer media, as it is not good value for
money. I can only think of one ot two applications where it is really
needed.

I think you are refering to the [RW] logo that identifies the DVD + system
as opposed to the DVD - system. There should be something under that logo
that gives the disks as write once only. I am not aware of any DVD RW9
disks in the marketplace at present.

It identified the DVD+RW format of disk. The logo came about because when
the format was first marketed, only re-writeable disks were available.
Market demand forced Philips to introduce write once disks, but the logo was
retained to avoid confusion (except it caused more confusion that it
avoided). Most members of the DVD consortium (particularly Toshiba) will
still not allow DVD+R/RW disks or their drives to display the regular DVD
logo.

The stylized RW is a trademark of DVD+RW Alliance, that'a all.
