Hi Scotte and welcome to the forum
I've seen the Pinnacle moviebox and think that it is very expensive for what it is. You do get the very good Studio 8 software, but it is around £100.
I would suggest you have a look on
www.dabs.com at some of the USB2.0 analogue capture devices from Dazzle, Belkin etc. They cost from around £40 and do exactly the same thing, just with different software.
I don't know the prices of the AIW's but would think they cost even more than this.
Mark.
