AVCHD / MP4 playback differences on computer and TV

Using Creative Video mode S (1/100ss) or flickr decrease creates another problem. You change the juddery motion to jumping or stepping exposure  

So no smooth video with GX7 / GHx automatic exposure.

​I'll don't actually own a GX7, just G5 and G6, but on the G6 that is certainly true for Creative Video mode 'S' (and is a real pain), but it certainly seems to behave differently i.e. have smoother exposure transitions, when using normal 'auto' (not iA/iA+) plus 'flickr decrease' with at least some Panasonic lenses (the 14-42 Power Zoom lens in particular).

I've never understood why Panasonic don't just offer at least variable, stepless auto-ISO in Creative Video mode - ISO adjustment is basically just video gain adjustment anyway, so why is it so difficult ? (the range could be limited if need be to say -/+ 2 stops - that would cater for many situations)
