I asked a co-worker recently: I've upgraded from XP/Pro to Vista - in XP/Pro I could use Shrink DVD 3.2 and Nero to burn copies of DVD's that we bought. The co-worker quickly told me that Shrink 3.2 would work fine - WRONG.
You have to 'purchase' Shrink, roughly $45USD - and this version works fine with Vista.
Motto is: Don't take everything you hear at face value. I had to learn through trial and error.
