How do I format interpreted videotape

I've got a trial with a videotape and an interpreter live translating the video for the judge. 

How do I format this and especially when she (the interpreter) continually stops her translation and says she does not understand whats being said in the language she is translating from. 

Thank you.  All help is appreciated.

When the interpreter makes a statement in the middle of translation, I do:

A.  I drove a red black yellow --

      THE INTERPRETER:  I do not understand what (whatever else is being said by the interpreter).

     (Discussion in Spanish between Interpreter and Witness.) - Assuming the interpreter turns to the witness and is clarifying the answer right after making the above statement. 

Obviously if the attorneys and/or judge asks the interpreter to clarify, you would identify them before "(Discussion in .....)," and then put the blurcb.

It's a little hard to put here, but if you would like me to send you my setup (which is depos, not court, testimony), please e-mail me at bigrotoo@aol.com and I will send you a few pages.
