do you hae premiere by any chance? I have a pinnicle card as well and when it actually works, I use premiere to save everything instead of Studio 7.0 or 8.0 whatever it is. Mine dosen't work... Grrrr... I bought the expensive one (350$).
But I think That is because My harddrive is to full, I need to go out and buy a new one just for my video capture stuff.
