First of all, sorry if the problem's obvious, I don't know much about computers and capture cards.

I want to record some footage from my XBOX 360 using the dazzle platinum capture card. The software that it comes with is not very good, it freezes my PC and takes a long time to load. I want to capture it using windows movie maker, but it doesn't seem to work. Every time I select "capture video" and error messages comes up, saying "the device cannot be read properly, close any other programs using this device." When this message comes up, there are definately no programs open that are using the device. I've tried the basic things, restarting my PC and taking out then plugging in the capture card, but it won't work. Can anyone help?
