PAL Xbox to NTSC TV help?

[fyalkowski]

I trying to use a modded PAL Xbox on an American NTSC rear projection HDTV. The Xbox is running Evo X/Unleash X. Under Settings, I've switched the Xbox from PAL to NTSC M, but the picture is still black & white.

Do I have to install yet another program? I've seen a lot of forums talking about Enigmah, but these posts are old, and I don't really trust that it's the most up to date way of doing things.

Thanks for helping a noob. It's much appreciated.
