I've been mixing for TV for years but I'm about to start my first 5.1 surround project-yikes! It's a TV drama-doc with some 19th century battle scenes. From what I've read here and elsewhere the standard seems to be to use the surrounds mainly for ambiences and music reverb returns. Surely there's licence to use them for distant gunfire/canon sounds/screams etc in battle scenes? I'd be interested to hear any cardinal rules or even useful tips you guys have regarding surround mixing - I just discovered this site and it's a godsend; I don't feel so alone anymore!
