Over all...I would reccomend that you look into something different to use than this card!
Hauppauge WinTV HVR-3000 Review | eolhc
While some fixes have been made the software is old and has not been updated...meaning that you might find some third party software options for that card out there somewhere.....in mean time...it really isn't a good card.
Also your computer specs are at the very low end for recomendations for the card.
