You'll need the following programs and tools to make dvdwizard work. Just install the neccessary RPMs / DEBs or compile them from source. dvdwizard checks each tool at runtime and won't get far if some are missing.
|dvdauthor||0.6.14 - 0.6.16 (tested)||dvdauthor
|ffmpeg||0.4.9 - 0.5.3 (tested)
svn20080206 - svn20090823
184.108.40.206 - 220.127.116.11 (tested)
|transcode||1.0.2 - 1.1.4 (tested)||tcprobe
The mentioned version numbers are the ones I developed the recent version of dvdwizard with, so these should be working. I don't know about any other versions, so you'll have to try.
