I'm having some problems with k3b since I changed DVD burners to a NEC
ND-1300A. AFAIK the firmware is at the latest rev. - 1.0B.
First off I can't write to a DVD as non-root anymore. The "Burning ISO9660
image" dialog box reports the error:
growisofs
-----------------------
:-( unable to GET CONFIGURATION: Operation not permitted
:-( non-MMC unit?
I get the same message if I attempt to read the mediainfo using
dvd+rw-mediainfo. I presume it's a permission problem somewhere, but where?
All that's changed is the burner. The /dev/ entries are the same.
Another problem is what is reported in Setting->Configure K3b... Devices. If
I look at the device properties as myself it says it can't write CDs or
DVD+ and Write Modes is listed as None.
Under Settings->Configure K3b... Programs it can't find dvd+rw-format. The
executable exists in /usr/bin, so why is k3b not able to find it? It finds
/usr/bin/cdrdao and /usr/bin/cdrecord so it's looking in /usr/bin ok. The
permissions on the executable are ok.
If I try to write to a 4x DVD-R I am only able to write at 2x speed. The
media is BulkPAQ orange which dvd+rw-mediainfo lists as:
# dvd+rw-mediainfo /dev/hdc

If I try the same for a Sony DVD writer I get:
$ dvd+rw-mediainfo /dev/cdrom

Write Speed #1: 2.0x1385=2770KB/s
Write Speed #2: 1.0x1385=1385KB/s
and k3b on this system allows me to write a 4x speed.
Is the problem that the drive is reporting 3.9x rather than 4x? Or is it
that k3b just doesn't understand the format of the drive report?
k3b version is 0.11.9 with FC2 running kernel 2.6.8-1.521.
