I'm pretty sure UE2 Runtime doesn't natively support AVI playback, but I know UnrealScript can access some dll functions. Could I access a very general system dll like the windows winmm.dll to play avi videos in Unreal? If not, could I write my own avi video playback routine in C++, compile it into a dll and call it from UnrealScript? Has anyone done this already or know where to find more info?
