I had a regular macbook, and I had all these little dongles that plugged in to convert things, and I thought they would work on the macbook pro... but there is no port for them. Now I am trying to find out how to get the best quality video from my macbook pro to my HDTV. I see some sort of large (DVI?) port on the back right side. I've never seen one of these. Is this what I would use? My tv only has a DVI cable that looks like a smooshed usb port, or component cables. Any suggestions?
