Hi Mike, you might want to look here for some more tips: http://processing.org/reference/libraries/video/
Prior to getting a capture card that shipped with a proper QuickTime vdig supported under under Windows XP and XPx64, I also tried a Windows wrapper called WinVDIG which I got from here: http://www.eden.net.nz/7/20071008/ However I found this version also crashed when responding the the QuickTime vdig API calls upon it. Also play close attention to the removal instructions for this stuff as it took me quite a while to clean my machine of WinVDIG and the crashes. Anyway the long and short of it is avoid this version and see below...

It looks far more up to date than the other one and apparently works with QuickTime7. This would be your best solution in the short term and I'll get back to you on this ASAP. The long and short of it is that I found the whole QuickTime SDK and integration with OSG quite a different experience under Windows and OSX. Pending some further funding and time I'd like to extend the current work to upgrade the "live/stream" work to use optionally DirectShow on Windows, and therefore free up the OSX version to use the newer OpenGL/CoreVideo/Movie QT7 stuff - right now they both share some old-style GWorld SequenceGrabber code to make it work on both platforms - you could say equally well or equally badly - and it creaks - especially the live stuff...
