nope. dont think its possible.
the only Hud ive seen moving is the running man and the loading icon on the loading screen. but nexon exported the running to frames then to .dtx then somehow program them to display them in order and make it look animated.
wmv. files wouldnt be possible even if u export all the frames, convert into .dtx, and wouldnt still work cause u dont have too many files to inject.
