I'd also like to add that vBTube looks to be an unofficial addon for vBulletin and not an official feature of the product...
For one, I don't really see throwing a video uploader into the UBB since I doubt more than a handful would actually ever make use of it, let alone have the resources to run it (you know, it takes resources to process an avi to a flash object; a lot of them, which just may make your webhost squeel with delight to click the off button on your site)...
I have enough trouble finding shared hosts for clients that allow exec to run ImageMagick, let alone convert videos.. Why? It's not security conscious to allow it...
