I am using a computer which has some multimedia capabilities. There is a PCI card attached to my motherboard that came along with the computer itslef when I first bought. There are several ports in that card and I can see all of them at the back side of my CPU case. There is one female RCA socket which is named as video in and an RF socket. I need to know what exactly the card features. Is it is the TV tuned card or a Video capture card or something different? I donít have much information about it because I didnít get any manual for this card. What may be the features of this card?
