To be fair...if the player is unable to move while they're watching things happen, that sounds like the definition of a cutscene.
You also have not clearly answered a number of questions that have been asked by people trying to help you, which seems odd. So I'll reiterate this (which was already said): during an autorun, other events that are set to parallel will continue to function.
So if you have events that are NPCs with autonomous movement, or images you want to animate, whatever, just set their trigger to parallel as was mentioned above.
If that doesn't work for you, then post screenshots of the various events you're trying to combine, but there's no reason having one autorun (to lock the player) and the rest parallel shouldn't work.
