First things first, you need to get a kernel with MTRR (more on this later) and DVD ioctl support. While MTRR's have been in the kernel since 2.2.11 (correct me if I'm wrong), you will probably need to update your kernel to get DVD ioctls. There are two ways to skin this cat, you can either download a development kernel (v2.3.x), or patch a stable release kernel (v2.2.x), the patches are at http://www.kernel.dk/, and the kernel can be found on your favorite mirror of ftp://ftp.kernel.org/.

Next, you need to get the LiViD utilities. This can be done two ways:

- Get the LiViD utilities from CVS, so you can update it as it is being updated by the developers. (recommended)

           The following commands will retrieve them (you can use -d parameter
           instead of setting CVSROOT if you want):

           # mkdir ~/livid
           # cd ~/livid
           # export CVSROOT=:pserver:anonymous@cvs.linuxvideo.org:/cvs/livid
           # cvs login
           (Logging in to anonymous@cvs.linuxvideo.org)
           CVS password:

           There is no password for anonymous, just press enter.

           # cvs -z3 co -P ac3dec mpeg2dec oms

           They should download into their respective directories.

- If you don't like CVS or can't access it due to firewall issues, you can download the most recent nightly tarball of LiViD tools at http://www.linuxvideo.org/developer/dl.phtml
