Also, with Yamaha you have the scene commands which can turn on the receiver, go to that input and set the surround mode for your usage. So, no need for input commands. You can have up to 8 scenes.

Unfortunately, in the database URC hasn't kept up with the naming of the scenes. Many years ago, the scenes were labeled TV, BD, CD, Radio on the Yamaha remotes. Today Yamaha labels them Scene 1,2,3,4 etc. but in many of the URC database codes they are still labeled BD, TV, CD, Radio. I think it is because the codes haven't changed just the names of them on the factory remote has changed. So try those commands if you want the scenes and you don't see Scene 1,2,4,4,etc. in the database.
