I am converting AVI files to DVD format for at home VCR and using Toast lite for burning the DVD. Toast lite will only allow 2 video files to be burned so I want to join files before burning. I am struggling with the join tool on ffmpegX. Which files should I join? Also, why the intermediate conversion to .avi.ff.mpeg and .avi.ff.mpg.DVD? Thanks. I have deciphered a lot of this myself, but some help would be appreciated.
