Dolby Digital Dynamic Range Control

Going through my setting for my TV Live Hub I noticed that there is now the Dolby Digital Dynamic Range Control. I have mine set to max but wondering if this is good or if there is another setting I should have it on. 

Not sure which is the best setting, you can find below how it is explained in the user manual.

" Dolby Dynamic Range Control (DRC) Setting Use this menu to set the dynamic range control, which reduces or increases sound levels. This setting can be useful when, for example, you want to watch a movie without hearing wide volume swings between loud and quiet sounds. DRC thus enables reduced peak volume levels without loss of overall sound quality. Default setting is On. Options are Off, Auto, and Max."
