I am using DVD Rebuilder 0.70 and CCE 2.5 SP and have followed the guide here as much as possible but get the message after about 10 minutes. There is nothing to do! DVD-RB couldn't locate appropriate files in working directory! You must PREPARE and ENCODE first. Aborting. In the output directory there are .bup .ifo and .vobs
better yet ... re-post your question in this thread: http://forums.afterdawn.com/thread_view.cfm/97052 The most experienced Rebuilder users check that thread often. Also the author of Rebuilder posts in that thread.
