That's neat! Although I don't think I could handle having to edit yet another dimension...haha.
Yes, seems, that I´m the dangerous man from the other dimension!
But seriously now: I´m really enthused by 3d-fotos and -films. With my Fuji Real 3d W3 I can make fotos and videos in 3d and I can watch them them on my Panasonic TV (with 3d-glasses). These fotos are so real memorials, it´s fantastic. I´m looking now, if it´s possible to post 3d-videos on YouTube and to watch them in 3d with glasses. May be one nice day I can make my first piano-video in 3d.
So I gave up and did all the audio syncing in Sony Vegas, which really does all the same things that Audition does, plus I could drag the files around more easily.
I see now, that you have had some difficulties and if the Sony Vegas does it in a better way, why not use it, of course.
Now I'm wondering about another thing: Do audio files play the same way for everybody? Meaning, does the computer, Internet connection, device or whatever, alter the way audio files play for people? For me, on my computer, the audio files sounded pretty well in-sync, but seems like it's not for you and some other people here.
I could imagine, that the speed of the internet connection could make a video out of sync, but I´m no expert concerning these matters. I suppose, prinicipally it could be possible, that these technical conditions could change the files. I also think, the idea of Scott is a good one. I will try to download your video with RealPlayer and see, if something has changed.
