DVD+RW burns 3GB but only reads back as 13MB

Further, when I experimented with the ProDVD with +RW media, I had to
tell it to ignore size, or I got the same error about over 100 minutes.

Note, this is with RH9.  Fedora is on another machine.

I use X-CDroast to burn DVD-RW's. But to do that with X-Cdroast (For
example) one needs to download another program to allow that to happen.
This site will help in that area

http://www.xcdroast.org/

With the Cdrecord.ProDVD file, I can burn the full 4.7GB's without a
problem (I use it for system backups too). Just take note that you need
a special key to be able to burn at full capacity (That info is shown on
the main page). There may be other ways to do it, but I found this way
much easier for me, and it may help you too.
