When watching films, especially movies that have a lot of action that takes advantage of the 5.1, the receiver just shuts off. The funny thing is that I'm NOT playing the movie loud. It has shut off at volume levels at 35, 33, and even lower at like 29 and 28. What could be the problem? I tried disconnecting all the wires and reconnecting, but had the same issue. Is it a setup issue regarding the speaker sound level or subwoofer? Is it that you have to play movies very low to prevent automatic shutoff? Is there some option I need to toggle on or off--maybe a mode that actually purposefully turns my receiver off even when I don't want it to? Could it be something else? Thanks.
