it could be this: Philips 713x TV tuner!???
I found this one and only link : http://www.mediafire.com/?m5gooxnozkl
it looks like an XP driver. I do not know the website, and nor would I be to quick to download something from a site I don't frequent. Be careful, and scan with Antivirus, to make sure it's okay.
You may also have to run as administrator to get a driver installed. As I said be careful.
Hope it helps you.
