Okay ya'll...here the situation I have a direct tv box in my office. I want to have this direct tv signal output onto my computer monitor. I want the footage to go through the computer in case I ever want to capture a tv show or something. What do I need to buy and what's the cheapest way to do this? The monitor has an input of either VGA or DVI. The direct tv box has an output of either coaxial, RCA (red, yellow, white), or S-video. cliffs: i need video transferred from my direct tv box to my computer monitor via a computer hookup. what do i need?
