vobcopy on breezy

['Forum Post]

Thanks for all your suggestions, with special thanks to Martti
Kuparinen.



XDVDshrink probably does the trick for a DVD9 but I'm focused on
getting one good DVD5 end-to-end copy, and for now I found neroLINUX
easiest way to go. NeroLinux is 30-day demo version so may have to look
again in February.



To install neroLinux version 2.0.0.4 I did this in terminal




Code:
--------------------
    cd /tmp

  wget ftp://ftp4.usw.nero.com/nerolinux-2.0.0.4-x86.deb

  sudo dpkg -i nerolinux-2.0.0.4-x86.deb
--------------------




Got a dependency message that hung the install but Synaptic Package
Manager in Breezy resolved that (xlibs) in a jiffy and located
neroLINUX installed in Applications > Sound & Video.



When neroLinux launched first time it told me me to enable DMA on
internal CD-ROM device /dev/hdc (it was disabled) and check all CD/DVD
devices' acess permissions. Nero lists exact chmod how to do the latter
(nice touch).



Hunted around how to change the DMA settings and found these simple
'instructions by Martti from Finland'
(http://users.piuha.net/martti/comp/ubuntu/install.html#12) for DMA
settings of IDE hard disk & IDE CD-ROM




Code:
--------------------
    sudo gedit /etc/hdparm.conf

  

  /dev/hda {

  io32_support = 1

  dma = on

  }

  

  /dev/hdc {

  io32_support = 1

  dma = on

  }

  
--------------------




which then continued with these further instructions




Code:
--------------------
    sudo /etc/init.d/hdparm restart
--------------------




SATA hard disk and IDE CD-ROM




Code:
--------------------
    sudo gedit /etc/modules

  

  piix

  ide-core

  ide-cd

  ide-disk

  ide-generic

  ...
--------------------




ending with Martti's instructions to test your DMA settings




Code:
--------------------
    sudo hdparm /dev/hdc

  

  /dev/hdc:

  IO_support   =  1 (32-bit)

  unmaskirq    =  0 (off)

  using_dma    =  1 (on)

  keepsettings =  0 (off)

  readonly     =  0 (off)

  readahead    = 256 (on)

  HDIO_GETGEO failed: Invalid argument
--------------------




When I tested in terminal I got 
Code:
--------------------
    unmaskirq = 1 (on)
--------------------
 otherwise all identical. Clueless right now about most of these
settings but nothing stopped neroLinux burning first an image in 8
minutes and then a Video DVD from that .nrg image on first try. Popped
the burned DVD in the stand-alone DVD Player, beautiful.



So for what it's worth that's how I accomplished the copy of an
unencrypted DVD5, stage 1. Stage 2 will be to shrink a DVD9 and burn
its shrunken image to DVD5. I confess DVD copying in Linux is a more
challenging undertaking than in Windows XP (omitted to mention how many
times today I tried K3b creating an image or burning to DVD only to have
it fail at 97% of completion, "mkisofs did not exit cleanly" or a
message to that effect...  maybe K3b just knows I like Nero).
