BlueCopter from the Green Button has posted a hack to get the Xbox MCE Extender to run in progressive scan! This is awesome, and I have been looking for this for a long time.
Copy the Extender program’s XBE to your PC, and open it in a hex editor. Search for ‘8B5728508B4730508B472C518B4F0452’ and change it to ‘508B4730508B472C518B4F04906A0090’.
This works for the standard version and rollup 1.
Awesome! Thanks BlueCopter! You’re a genius!
