Any ideas on why Open() would fail?

Tried to reply to this yesterday but the Forum told me I had exceeded my daily quota of 3 posts. What the heck is that? makes it kinda hard to keep up a conversation and I had only made the two post the day before..

Anyway, not sure I get what you are saying, I am positive, without a doubt nothing else is using the capture card resources when this fails. As I've stated it works great on every computer except this one. I have even ran the Advanced Video Capture app on my development computer at the same time I ran my software. This created a conflict with both programs trying to access the same capture card. All it did was not display the video on whichever app I started 2nd. VLDSCapture1->Open() still worked as expected even though the first app was open and displaying video.

I need some kind of hook that will tell me why VLDSCapture1->Open() is failing on a computer 1/2 a world away.
