I don't see what the problem with HDR video is? It's meant to change ISO levels in the display to let you preview the two light levels you'll work with.
If you mean on playback it changes ISO, that's how it's supposed to be. Look at the documentation I linked you to before (http://wiki.magiclantern.fm/userguide#hdr_video).
If it's something beyond those two, then I guess you have found a unique bug, but you'll probably need to describe it better.
