One con about this MSI card is that the included PVR software doesn't seem to work with Windows XP. I've tried a number of other programs like SageTV and ChrisTV, but to no avail. I don't really care about the TV aspect of the card that much though, and Media Player Classic (believe it or not) actually works well as a video player, so I can still watch TV through my cable box.
So I guess I'm not going to worry too much about my TV software not functioning if I change the capture card drivers.
