OK, I've tried the Heroglyph plugin's Vitascene and ProDad and they ran, Some New Blue FX plugs ran, but others did not, and of course all VASST Plugs I've tried have run.
I've had some NewBlue FX filters crash my vegas 8 (in 32bit mode at least). I had the magic Bullet 2.0 and it worked but it was a little weird in 32 bit, and as anyone who has these would know, the Velvet matter plugs don't appear.
Hope this helps anyone out there who's been wondering
