+Q: Compiling K3b fails with errors like this:
+ base_k3badvanceddataimagesettings.cpp:185: invalid use of undefined type
+ `struct KComboBox'
+ base_k3badvanceddataimagesettings.h:17: forward declaration of `struct
+ KComboBox'
+A: The QTDesigner tool 'uic' is not able to find the kde widget plugins.
+ To solve this run 'qtconfig' and add '$KDEDIR/lib/kde3/plugins' to the plugin search path
+ (replace $KDEDIR with your kde base dir).
+
+
+Q: K3b thinks my SCSI device is IDE.
+A: If you are using the rpm from SuSE your version of K3bSetup is not able to set the
+ permissions that K3b needs the devices to have. The SuSE guys seem to think messing with
+ permissions is too dangerous. It is recommended to always compile from source to have all
+ K3b features.
+
+
+Q: Where has all the fancy graphic gone?
+A: Most likely you installed K3b in the wrong directory. All KDE programs are installed in the
+ KDE dirtree (SuSE: /opt/kde3, RedHat: /usr). If you compile K3b from source it defaults
+ to either $KDEDIR or /usr/local. To install in the correct directory you need to specify the prefix
+ to configure like this:
+ ./configure --prefix=`kde-config --prefix`
+ That will install K3b relative to the correct path.
+
+
+Q: The linking always breaks with the missing -laudio.
+A: You need to install NAS.
+
+
+Q: Where can I find K3bSetup2?
+A: K3bSetup2 is a KControlCenter Module. You can find it in the System Administration section or start
+ it manually with "kdesu kcmshell k3bsetup2".
+ There also is a script since K3b 0.11 called k3bsetup.
+
+
+Q: My writer supports writing at speed X but K3b shows Y as a max.
+A: K3b determined the maximum writing speed the first time you start it. Since the speed reported by the
+ writer always depends on the mounted medium this may not be the real max.
+ To manually change it open the K3b settings in the device section and click on the value. You will
+ be presented with a spinbox which allows to change the speed.
+
+
+Q: Writing fails with the following cdrecord message:
+ "Cannot allocate memory. Cannot get SCSI I/O buffer."
+A: Since kernel 2.6.9 suid root programs are not allowed to use the SCSI subsystem.
+ To solve this issue either configure cdrecord to run without root privileges: chmod 755 /usr/bin/cdrecord
+ or run K3b as root (which is not recommended but works also).
+
+
+Q: Writing fails with the following cdrecord message over and over again:
+ "Error trying to open /dev/hdc exclusively (Device or resource busy)..."
+A: You are using a patched cdrecord version which tries to open the device exclusively which fails because
+ your are probably also using automounting. The solutions are to disable automounting altogether (and this is
+ the recommended solution as automounting can cause other more serious problems with CD/DVD writing) or to
+ install a non-patched cdrecord version.
+
+Q: My DVD drive supports 16X but K3B keeps burning at 1X! What's happening?
+
+A: Your kernel most likely didn't apply optimal settings for your drive when it detected it. You can find out
+ what are the current settings of your drive with the command "hdparm -v /dev/dvd":
+
+ /dev/dvd:
+ IO_support = 0 (default 16-bit)
+ unmaskirq = 0 (off)
+ using_dma = 0 (off)
+ keepsettings = 0 (off)
+ readonly = 0 (off)
+ readahead = 256 (on)
+
+ The following options are known to maximize burning and playback performance:
+
+ hdparm -d1 -c1 -a8 -u1 /dev/dvd
+
+ To make these options permanent, a quick and dirty solution is to include the command in /etc/rc.local.
+ Consult your distribution documentation for a tailored solution.
+
+ Some drives have buggy DMA support. If you experience instability, leave these options disabled.
