Wierd Orig. Xbox Problem

I modded my Xbox a few days ago using the hotswap method, everything went fine and I now have UnleashX 0.38 installed.

But my North American Xbox now outputs PAL video and plays Region 2 DVDs :confused:, it still plays North American games, and thankfully, my screen supports PAL, but I plan to take it to my friends house at some point and I don't think his TV supports PAL video :(

So I want to know:
1: Is it possible to switch it back without restoring my HDD backup?
2: Which file controls this stuff? (if any)
3: If the answer to 1 is yes, and it isn't a file, then how would I change it back?

I don't care about the DVD region, just the video output

Nvm, I found a fix.
The "Enigmah video mode boot disc" allowed me to switch back to NTSC!:D
