Problems burning files to DVD+R

Sun Apr 8 09:14:14 BST 2007

Running Ubuntu Edgy on hardware which hasn't changed since last year
July using media from the same stack of 50 I've been using for three
months I've suddenly run into a complete inability to write to DVD+R.
When I try to go through GNOME, here's the sequence:

1. I put the disk into my (external, USB2) DVD+R drive.
2. GNOME detects the media and asks what I want to do.
3. Whether I give it files in the burner interface or tell it to go away
and try to burn a premade ISO file, I get, instantly, with no hint of an
attempt to access the bus, a dialog with the following message:

        Insert a rewritable or blank disc
        Please put a disc, with at least 3.6 GiB free, into the drive.
        The following disc types are supported:

The list implied by the colon is empty.  What you see above is the
entire message.  So, deciding that maybe I'm going to have to go to the
command line to solve this, I switch to a shell and type:

$ dvdrecord -scanbus

$ dvdrecord dev=1,0,0 -dao Movies_5.iso

At this point I get activity on the drive, at least -- it doesn't puke
up a meaningless error message right away with no hint of activity.
Instead it churns on the drive and looks for all the world like it's
doing what it's supposed to be doing.  For about 15 seconds.  Then I get
this:

At this point I don't know where to even begin to continue.  What's the
next step in getting one of the following to happen:
a) GNOME's burning interface working the way it worked before instead of
not even trying before throwing its hands up in seeming ennui.
b) As a distant second place in preference, dvdrecord working (or at
least giving useful information explaining why it's not working instead
of hexadecimal vomit).
