There shouldn't be any noticeable difference between the PVR version of the PCI WinTV card and the standard PCI one. It's only with the USB one that there is an improvement in quality. All the PVR PCI card gives you is compression of the videostream without needing your CPU.

The card should come with some basic capture software. If you get serious about it then something like Ulead Videostudio would be okay to edit the files.
