    Kind of a personal preference I guess, I usually leave it off for movies but it can keep commercials from blowing your ear drums. It can also limit the range in a movie if you feel like you have to turn it up loud to hear to vocals but explosions etc. are too loud, saves you from reaching for the remote the entire movie.

    So by volume compression do they mean lossy? Does it take away from lossless audio or is that a different compression?

    It's not changing the format or losing anything, it's just taming the volume spikes and bringing up the lowes to a more even level. Think of a movie where a quiet conversation is taking place followed by a loud action scene. If you're having trouble hearing the dialogue and then all of a sudden the action scene is so loud you have to turn it down, it keeps everything on a more constant level.

    Here's a link that can explain it a little better: http://www.audyssey.com/audio-technology/dynamic-volume

    I like dynamics in audio, so I leave it off. I will only use it at night when others are asleep so I can keep the overall volume level lower.

    Off because I like to hear the movie they way the sound engineers intended it to be heard. Plus I try to limit unnecessary processing as much as possible.

    Why is everything louder while using dynamic volume compression? I had my volume down to 20 and I could barely hear anything while the dynamic volume was set to off...but when I turn the dynamic volume to light it is louder. I would think that dynamic volume set to off would be louder, no?

    In theory, with dynamic volume OFF, quiet sections should be quieter, and loud sections should be louder. Every receiver is different though, so how your receivers does it may vary from a different company.

    When it is off, the signal is unprocessed and the result is loud parts are loud and quiet parts are quiet. When it is on, the DSP brings the lows up and the highs down, making for a sound that is less dynamic; hence the name. However, the process in which the high and low dynamics are compressed my result in a final sound that is nominally louder than the unprocessed signal.
