If you are trying to use the component video, it won't work. There is extra information included in component video sent.

If you want RGB you will need to hack an xbox SCART cable.  As DarkKobold pointed out, it sounds like hacked an HD-pack (component) cable (I can see how you might be confused as the Y, Pr and Pb wires are also red/green/blue).  Component or RGB has the best output.  Of course you need a component capable TV to view it (at 480p).  Or you can buy a Component-to-RGB transcoder to send to an RGB monitor (at either 15khz or 31khz).

Read the Game Consoles FAQ on this site for more.
