I'm about at the point of extreme anger towards this "wonderful" piece of software

I have a DVC 100 all rigged up to the Xbox and am able to capture using Movie Maker and Instant DVD recorder and also see the preview in AMcap

But low and behold when i open Studio 14 i get either "no input signal" or "failed to...something something(cant remember)"

Is this able to capture SD or have i dropped the ball on this one????

Any help gratefully appreciated
