I'm not interested in capturing videos, but I take it that what you have is not put into the computer. It's an external card, right? You can hook in the RCA cables, a place to plug in the speakers, and the monitor cable, and that's how it works I'm assuming. I'm looking for something internal, so I can also get cable on it, and not have to worry about unhooking my monitor from the computer. I think I found something here though, and it has what I need.
Tuner Card
This has the audio in, and I have an adapter that converts RCA audio cables into one of the regular cables used by computer speakers(the typical green plug), so I can just plug my RCA audio(white and red) into this tuner card. The RCA in is there, except they call it the AV in which is where the RCA visual(yellow) plugs in. Then I just have to put the cable in there as well if I want to watch tv.
Can someone confirm to me if what I said is correct? I just want to make sure that I'm getting the right piece of hardware.
