DVD+R DL Help

[tamman]

I currently own a DVD+R DL burner and I went out and purchased some dual layer Verbatim media. Upon inspection of the media I found two labels, a RW label on the box, and a DVD+R DL label.

This confused me a bit and I have the following questions which I hope someone can help me answer.

1/ Is the media rewriteable at 8.5GB (Dual layer)?
2/ Is it the case that it's rewriteable at 4.7GB OR single-write at Dual Layer?
3/ If (2) were true, then if I use it as a 4.7GB re-write can I then wipe it and use it as a 8.5GB Dual layer?


Thanks!

The are no DVD+DL rewritables, unfortunately.
From what i understand, even if they could produce the DVD+DL RWs, they would be unreadable by most DVD players.

The case says RW because RW is the symbol the + side uses, but that doesn't make all their DVDs rewritable.

Some vendors were packing a set of some single-layer discs plus some DL in the same box (for example 8 SL + 2 DL = 10 disc box). It sounds like you are looking at one of those.

The problem is that the "+R" format guys, are calling themselves the "DVD+RW consortium", or something like that, and their logo that they put on the discs is a box with a bold "RW" in it. I had to do a double-take looking at the packaging for some Maxell DVD media, because I thought that they were +RW (re-writable) media as well, and couldn't believe the low price. Turned out that they were just +R.

Highly misleading, IMHO. They should just use "+R" and "+RW", just like there are multiple "Compact Disc" logos as well, for audio, data, and some other formats too.

(Worse yet, -R and +R media have different total sizes too!)
