So let me get the story straight....
The IFE wasn't working immediately after the flight took off already.
Yet your two kids wanted to sit together to watch a movie together. Well after the flight took off, the IFE would have stopped working already. So what was wrong with going back to the original seats you were assigned to??
There might have indeed been an error in the rule the ISM cited. But this story sure sounded like two adults who wanted to sit in J regardless. Especially when this happened even before your kids wanted to watch movie together:

Next time, use your 'hard earned points' and just redeem four seats together in PEY or Y if you really want to be seated together. Problem solved.
