I've been using an IFOEdit-based method to shrink and re-author dual layer DVDs to DVD-R. This keeps just the main movie with a choice of audio & subtitle streams and sets the movie to start automatically after DVD-R is insterted in player. After some trial and error I got it working OK and I'm now wondering whether I can add a small intro video before the movie, so that I can "tag" my DVD-Rs. Is there any way to do such a thing in IFOEdit? If not, is there any DVD authoring program that would let me import the "IFOEdited" VOBs and IFOs and add the intro there, without messing with the rest of the content?

Cheers to all.
