I have searched relentlessely, and almost bought NeroVission Express 3 to convert an Mpeg2 file into a Vob file from some home movies I imported off a DV tape, until I finally bumped into this utility, and its free!!!
VSO, keep up the amazing work, especially on things like this, that you make available to the public.

According to the revision history, this is the last free version, so grab it while you can.
So far my encodes have no loss, hands down guys!!!
