I've had some trouble aswell with this.
To be honest, the replay theater lacks a lot of functions.
For instance, you should be able to manually rewind and skip or skip to a certain minute.
I think a custom camera (like the one in call of duty) would be really good.
Also the function to change the speed, for example 50% or 25% would be nice.
and for the display, there should be atleast the function to turn off the names, because it's really in the way of everything.
