Curtain Calls and Scene Changes

For some reason, when watching an opera video, I really dislike seeing the curtain calls between scenes and after each act. But I don't mind at all seeing behind-the-scenes stuff.  In the Met HD Elisir, I liked seeing the (excruciatingly long) set change between scenes in Act 1. In the Neuenfels' Lohengrin you can see the chorus getting ready for the final scene, and during the prelude to Act 3, there is a specially produced video of backstage stuff. But those are video-only bits. The audience in the opera house doesn't see that. It's part of the video production. 

This video continues past the Act 3 Prelude. 

The mice/rats singing of the Bridal Procession 

is pretty cool (and yes, a little weird.)

I guess that maybe why it doesn't bother me. Scene changes don't take me out of the drama, because changing the scenery is part of the production. I enjoy the mechanics of theater. Sometimes you even get to see the scenery changes right on stage (e.g., the wonderful Minghella Butterfly) and those changes really are part of the show.  Somehow that artificiality is not distracting to me.
