Turning off hardware acceleration and fast feedback has makes no difference.

Okay, that was easy, simply uncheck loop to starting scene in export options! Shame Sketchup doesn't have a more efficient, multicore, video encoder.

Ah well, all the others above suggested the same - I just thought a model can demonstrate it easier. Be very careful however to only assign groups or components to any other layer than Layer 0 (i.e. all "primitive" geometry either loose in the model or inside groups/components should remain on this layer) otherwise you end up like in that first video you linked to. Do not even change the active layer (with the round radio buttons) but stay on Layer 0 all the time. Life will be much easier. Also, examine the Scene manager. If you turn off the camera position, you can change scenes (and with those, different layers) without the camera moving. If you watch this video, during the first quarter, Chris (who posted above) explains how he uses scenes, layers and styles for easier modelling. Not exactly what you are after but very informative! http://www.youtube.com/watch?v=r9_F-bSGrKs#!
