I totally understand but i dont see how this m$ fault the developers of Pinnacle Studio should have been well aware of the release of vista and had plenty of time to get there software to work for it.
Everyone who develops software has been able to get there hands on vista for ages.
My mate is a developer and he says that the new vista is alot easier to code for.
Im not a m$ fanboy. I have had both PC's and Mac's.
