How do I find what type of tv tuner card i need for my laptop

Go to a Best Buy or equivalent and ask. Pavillions are pretty basic home use systems therefore wont need anything super specific when it comes down to a tuner card. Windows 7 compatible (will say it on the box) and you should be good.

I tossed the box when I first got it but I still have the instructions and what not I'll have to look at them I was hoping for a download for one lol.
