Uh -- first, those instructions *do* work if you follow them. Second, if it's Vdub, you *do* have a menu choice that says "streams." If you mean that it's empty, that might mean you have no sound, which as the instructions say, is fine since you don't need the source's sound for vidding.

Honestly, I think you might benefit from slowing down a moment, and working with the instructions and the guides one step at a time, slowly and carefully. Don't leap to the conclusion that something doesn't work the second you run into a snag. I've found that when instructions don't work, 9 out of 10 times it's because I've made a mistake somewhere along the line.
