Capture Card for Mac

[InsanelyApple]

I'm wanting to record myself playing games on my Wii, and have it where I can commentate the games. I have one of those old SD TVs.

Now what I need to know is:

What capture card do I need?
What accessories do I need?
And anything else I need?

I have the EyeTV 250 Plus and I know it's possible to record your Wii playback. I don't know how you would commentate on the videos though you MAY be able to do it via iMovie. Check out the link for more information. Hope this helps. I would also look on Elgatos website to see if any of their other devices have the same ability to connect your Wii.
