I'm using a 1.0 template in 1.5 for a client obviously running in legacy. I tried two other plugins to play youtube videos and neither would work in this scenario. MgMedia worked perfectly with no trouble. It is more complex than the simpler plugins but there was no configuration to do. And it is very powerful in the media types and methods that it can do.

I would suggest simpler documentation for playing youtube as that is probably the majority of it's use. It will be or is intimidating to the newbie without this. Other than that a Fine piece of work! ich gratuliere! I hope that is right.
