It works like a charm, wholly intuitively. I've been trying to make (editable) QT movies out of an old, long-ago copied DVD, which presented me with problematic (for me) ".VOB" files, and have tried a few conversion apps to no avail (OK, maybe the wrong ones, but that was my experience). With this it was a breeze. It seems a bit slow, but then, they're big files, and this doesn't detract from my 5-star rating. And all this for a bargain-basement price. Wow! I didn't comment on "Support/Documentation" because I have had no need for either, so far. That's good.
