VisionLab doesn't contain any stock footage. Stock footage can't be stored within the program, it has to be imported as media into whichever project you want to use it in, so none of the Footage DVD's contain anything already in VisionLab.
However, the specific DVD you mentioned does include a bunch of clips based on the old AlamDV plug-ins
that are available for download from the site. There is other stuff on the DVD as well, so its not all stuff that's already available. And as far as the AlamDV plug-ins, on the DVD they have already been converted to video clips for convenience, and it saves you the trouble of downloading them all before you can use them, as there are loads. That is the only DVD that contains content available elsewhere on the site though, and as I mentioned before, there is also pyro content on the disk that isn't downloadable from the site.
