Video recording of the orientation is a great idea. Anita in the sales office suggested it to us, and our video recordings helped us on one occasion.
One suggestion, though. Instead of one long video of the entire orientation, periodically stop the recording, and then restart when they are introducing a new system. Then take the video files and rename things like MaxxAir.mp4, SolarControlPanel.mp4, and Thermostat.mp4. Then put them somewhere where you can find them, in my case on my Dropbox.
On our first trip, we could not get the thermostat to start the furnace, and the owners manual did not help. But the Thermostat.mp4 video explained how to use it, and we did not have to go thru a three hour video recording.
