Update -
My Ex-box is now my x-box again. Yeah I modded it a few weeks ago, but I hadn't gotten round to setting up the network stuff, plus I didn't have a backup of my eeprom, so the enigma switcher really was my only hope (other than find a pal TV / buy a TV card). I must have gone through over 20 DVD's, burning the image as it was, padding it out to make it bigger, taking an Iso disc I knew booted fine (Ie Slayers install, my Chronicles of Riddick backup) and replacing the default.xbe with the one from Enigmah. In the end I think just the original enigmah iso, burned at 1X did the trick. I had pretty much given up hope, and had even swapped out my Sony DVDRW drive from my PC and was booting with that (and yeah it booted my games fine). It's been a learning experience for sure, won't be touching that option again in a hurry....thanks for the replys though, it's appreciated.
