Godot's Cd & Dvd

# use the program xine-check to determine whether your cd/dvd software (e.g., mplayer, ogle, xine,...) is configured optimally:
```
xine-check 
```
# enable dma for your dvd player:
```
sudo hdparm -d1 -X34 /dev/dvd 
```
If you are satisfied with this setting, consider appending its specification to /etc/init.d/bootmisc.sh:
```
echo hdparm -d1 -X34 /dev/dvd|sudo bash -c "cat >> /etc/init.d/bootmisc.sh" 
```
# the program k3b, part of the kde tools, provides a very nice user interface for writing cds and dvds:
```

Tips To Write/burn Cds

# initialize the variable ISO_DATA which points to the information you wish to write to a cd/dvd, and the variable ISOFILE which specifies name and location for the cd/dvd image:
```
 export ISO_DATA=/home/$USER
 export ISOFILE=/tmp/image.iso
 sudo ls -al $ISOFILE 
```
# create the iso image, write it to $ISOFILE and make it contain all files found in $ISO_DATA (including all subdirectories):
```
 mkisofs -J -r -o $ISOFILE -R $ISO_DATA 
```

# test the newly created iso image (optional step):

 sudo mount -t iso9660 -o loop,ro $ISOFILE /cdrom
 ls -alR /cdrom
 sudo umount /cdrom

# find out which cd/dvd writer can be used:

 export CDWRITER=`sudo cdrecord -scanbus|grep RW|head -1|cut -f2`
 if [ :$CDWRITER: == :: ];then
   export CDWRITER=`sudo cdrecord -scanbus|grep DVDRAM|head -1|cut -f2`
   fi
 if [ :$CDWRITER: == :: ];then
   export CDWRITER=`sudo cdrecord -scanbus|grep SD-R2512|head -1|cut -f2`
   fi
 if [ :$CDWRITER: == :: ];then
   export CDWRITER=0,0,0
   echo REMARK: your cd writer device could not be detected automatically...
   echo REMARK: using $CDWRITER as default device...
   echo REMARK: check whether your default device behaves properly with:
   echo sudo cdrecord -scanbus
   fi
 echo we will be using device :$CDWRITER: to write your cd/dvd to...

# if you wish to clean an existing cd/rw, you can burn the data with:

 time sudo cdrecord dev=$CDWRITER -blank=fast -v -eject $ISOFILE

# if you are using a blank cd/rw, you can burn the data with:
```
 time sudo cdrecord dev=$CDWRITER -v -eject $ISOFILE 
```

Tips To Burn Dvds

# how to burn a DVD-Video under Linux with mkisofs and dvdrecord
# how I burn the information found in $DATA_FOR_DVD on a dvd+rw using linux (and a sony dvd/cd rewritable drive unit model dru-500ax which is found at /dev/dvd):
1. # specify where the information for the DVD can be found, where the temporary iso file can be stored, and the name of the DVD iso image:
```
 export DATA_FOR_DVD=/tmp/dvd 
```
2. # clean the dvd+rw:
```
 sudo dvd+rw-format -force /dev/dvd 
```
3. # perform the writing (master and burn an iso9660 volume):
```
 growisofs -speed=2 -r -T -multi -overburn -Z /dev/dvd $DATA_FOR_DVD 
```
4. # append more data to an already mastered volume (make sure to use the same options for both initial burning and following sessions):
```
 growisofs -speed=2 -r -T -multi -overburn -M /dev/dvd $DATA_FOR_DVD 
```
5. # perform the writing of a pre-mastered iso9660 volume to a dvd:
```
 growisofs -speed=2 -dvd-compat -r -T -multi -overburn -Z /dev/dvd $DATA_FOR_DVD 
```
