Try uninstalling all the drivers and plugging the card into another spare PCI slot. This time try installing the drivers manually from device manager for the new hardware and then install any PVR software like Chris TV,... Just make sure the device components are recognized correctly. If there are no issues with the driver installation, the card will run fine. The bundled pvr softwares are often buggy and have many issues. That is why chris tv and likes are better options.
