An article by Robert Edwards, discussing aspects of mixing TV sound in 5.1 and surround.

"The plan’s the thing: Mixing surround sound for TV
Mixing 5.1 surround audio for HDTV production is more than just moving faders."

The article appears in Broadcast Engineering, here.

"The purpose of this article is to discuss some of the surround mixing techniques I have developed through this work and other projects, but the fader-moving part of live mixing for broadcast is often the easy part of the process, relatively speaking; the more involved part by far is the planning and preparation."
