You'll have to elaborate a bit. Are you using your own behaviors for movement? What do you mean by "sides of platforms"?
The cutscene pack replaces the miscellaneous pack, as it contains everything in the miscellaneous pack and more. Both packs have the "Player Control" behavior for platformer movement and it works pretty well. Issues with actors getting stuck while using it would mean problems somewhere else, such as the actor's friction settings, or if your player is standing over a row of missaligned actors.
