I just noticed something that I didn't know or didn't notice before. It is possible to hide a Prim containing an image. But if a Prim is playing a video, it will not be hidden.
Now, you may ask, why do you want it hidden? The prim is being used for a hologram TV screen. IF I have to delete it, I would lose a very important voice marker to line up the videos,
which I don;t want to do. I wish I could just hide a Prim with a picture or video. It should not matter. Am I doing something wrong?
I end up just deleting the video prims, since they can not be hidden. I wish they could be hidden and instead just getting the sound from the video...
