Here's the thing, I rarely ever use video which is why : Fn1 is set to record Fn2 is set to magnify Rec is set to MF (alternates between AF and MF) Mainly because half the time I'm either manually focusing or I'm using an adapted lens. But I noticed that if for example if I switch over to Video mode, the settings for Fn1/Fn2/Rec will show as "Off", so I'm thinking, "Oh does this mean I can set a different set of custom buttons when I'm in the movie mode?" Such as re-assigning Fn1 or Fn2 to the digital teleconverter while I'm in movie mode. Apparently it is not the case, because if I set anything to the buttons in the custom menu while in video mode, those changes carry over into "M" mode which I am in 90% of the time. Why does it even bother to say 'off' over in movie mode if I can't set them independently to shooting modes?
