Decording mode for TV

As a newbie I'm a little overwhelemed by some of this but am enjoying learning. I'm trying to get a handle on dolby digital decording modes and the differences. I have a Denon Avr-1082, can anyone advise what the right mode for watching tv is?
I've already discovered I like the "widescreen" format for movie viewing, gives lively sound.
Thanks for any help.
Try experimenting. What's best is what sounds best to you in your room with your system and your acoustics.
With your Denon , your receiver should be set to pro logic, then pop in a DVD, select Dolby Digital from the menu, press enter, then play, and Dolby Digital should light up on the Denon.
Then your wife will yell at you.
