HoliScapesAtmosFX® Halloween Digital Decoration on USB Includes 8 Atmosfx Video Effects for Hallloween

Can the dvd be copied? I have two projectors.

Do you need to have sound for this to be entertaining? I want to play rear projection from inside my house but people outside won’t hear it.

Can the videos be set to play on repeat or will someone have to hit “play” every few minutes?

how long is the video? Can I run it on a loop?
