Capturing Xbox 360 game with EasyCap: How to connect Xbox to monitor via VGA?

[MightyBananas]

Hey there please help!!!
I've looked around and there's nothing that can help me with my little problem here.

I've got a PC monitor that can only take in one VGA input. Right now I have my PC hooked up to it via VGA. I was wondering if there is any way that I could hook my Xbox up to my PC monitor and have my PC connected to it also. Something like a VGA Splitter + VGA/Composite converter so that I could have both Xbox and PC plugged in and be able to switch between my Xbox and PC input? Basically what I'm trying to do is capture with my EasyCap but be playing on the same display that my PC uses. Is there any way to do this?
