ok here it is, i havnt bought a capture device yet because 1. im a noob at the whole capture thing and 2. want to get more info beore buying, so i welcome links.

my setup is: my xbox 360 is connected to my flat screen 19" monitor (here is the VGA cable im using http://www.xbox.com/en-US/hardware/x/xbox360vgahdcable/ ) and the VGA cable LR audio male is connected to a y adapter to my computer. i have external speakers that are connected to a sub woofer so i can turn up bass while playing games, the xbox does NOT connect directly to my sub woofer or speakers. the 360 can only support VGA and not DVI so thats why i used VGA. i can post pics if needed.

please tell me what i need to get and what type of capture device i should get, preferably under 100$
