Chapter mode isn't supported. You can't use PSU core. You can't transcode a frame range, always the whole movie is transcoded Title needs to be copied on harddisk, no on-the-fly or DVD image transcoding possible. 3.2 Architecture overview [Content] [Top] A dvd::rip cluster consists of the following components: A computer with a full dvd::rip and transcode installation, DVD access and local storage or access to a NFS server, where all files are stored. A computer with a dvd::rip installation, but no GUI access and no transcode installation, where the cluster control daemon runs on. This may be the same computer as noted under 1 (which is usually the case). An arbitrary number of computers with a full transcode installation, dvd::rip is not necessary here. These are the transcode nodes of the cluster. The GUI dvd::rip computer and the transcode nodes must all have access to the project directory, shared via NFS or something similar. It doesn't make any difference which computer on the network is the NFS server. The communication between the cluster control daemon and the transcode nodes is done via ssh. All transcode commands are calculated by the cluster control daemon and executed via ssh on the transcode nodes. dvd::rip assumes, that the cluster control computer has user key authentication based acc

"dvd::rip is a full featured DVD copy program written in Perl. It provides an easy to use but feature-rich Gtk+ GUI to control almost http://www.flattermann.net/2010/10/dvdrip-how-to-solve-the-avi-file-has-no-video-data-problem-in-cluster-mode/ all aspects of the ripping and transcoding process. It uses the widely known video processing swissknife transcode and many other Open Source tools. dvd::rip itself is licensed under GPL http://osdir.com/ml/video.dvdrip.user/2003-09/msg00098.html / Perl Artistic License." It works pretty good and can also make use of multiprocessor CPUs by using the "Cluster Mode", i.e. you start n nodes on your dvdrip cluster PC and dvd::rip will do the load balancing. Unfortunately, some users (including me) have encountered a problem in cluster mode: The process will stop with an error of "AVI file has no video data" for PSU1 while merging the video files. http://ubuntuforums.org/showthread.php?t=819529 http://forum.ubuntuusers.de/topic/dvd:rip-cluster:-fehler-beim-merging/#post-964897 http://www.exit1.org/archive/dvdrip-users/2007-04/msg00049.html The strange thing is that the source material only has a single PSU (Program dvdrip cluster error Stream Unit) with actual data (PSU0). PSU1 is empty, therefore transcode will throw this error. Encoding the material in normal (not cluster) mode works, but it does not make use of your multiprocessor CPU and is therefore pretty slow. I've applied a small hack to one of the Perl files so that very small PSUs (< 100 frames) will be ignored by dvd::rip. For me, this has fixed the error and dvd::rip encodes the material without problems. To patch the file, open the file /usr/share/perl5/Video/DVDRip/Title.pm and change the function calc_program_stream_units (around line 1205) from: sub calc_program_stream_units { ... if ( $last_frame != 0 ) { push @program_stream_units, Video::DVDRip::PSU->new( nr     => $current_unit, frames => $last_frame, ); } ... 1; } to: sub calc_program_stream_units { ... # Hack to remove very small PSUs (<100 frames) # Christian Erpelding, http://www.flattermann.net # 2010-10-26 if ( $last_frame >= 100 ) { push @program_stream_units, Video::DVDRip::PSU->new( nr     => $current_unit, frames => $last_frame, ); } ... 1; } PS: I'm using dvd::rip 0.98.11-0.0 from the Debian Multimedia Squeeze Repository (debian-multimedia.
