I use Ripit4me to get the dvd to the disk. Once on disk I use DVD Shrink in IFO mode to join the .vob files of the main movie into one big 4GB or so .vob file. Then I use Videora Ipod converter to get it into .mp4 format.
I am currently testing out Mediacoder with the Ipod plugin to convert from .vob files to .mp4. Mediacoder looks good but always crashes for me when I open the settings since I didn't bother to install firefox. Mediacoder seems to have a "join" mode which could handle the 1GB .vob files, not sure how to use join mode yet.
So I mostly use Mediacoder when I am dealing with a .mpg file and its fast, and Videora Ipod converter with DVDs.
Anyway I am looking forward to seeing new and improved versions of Videora Ipod converter and Mediacoder.
